I think we should improve the readability of the diagnostic event and stack trace outputs that the environment generates on the console and in tests when there are failures.

This is not about improving the contents / data within the diagnostic events, and only the presentation of the existing data, so it is easier to glance and digest.

An example of the existing output as of v21.2.1:

thread 'test::test_sample_policy_call_self' panicked at /Users/tylervanderhoeven/.cargo/registry/src/index.crates.io-6f17d22bba15001f/soroban-env-host-21.2.1/src/host.rs:768:9:

Some examples of panic outputs in different environments for inspiration are below. They use very simple inputs, so their utility may be limited, but maybe we can learn something from them. I also understand that the diagnostic events are not stack traces, and they don't point to code, but developers sort of treat them as similar, as a way to understand where the program was when something went wrong.

Rust 
fn main() {
	f1(1)
}

fn f1(i: u32) {
	f2()
}

fn f2() {
	f3()
}

fn f3() {
	panic!("oh no")
}

My main interest is mostly just readability. So adding more whitespace and line breaks would go a long way towards legibility.

You could further break up arrays by comma if you wanted to but that would start to make stack traces very very long.

Idk if we have the ability to color anything but highlighting actual error messages would also be really nice.

e.g. from above these are really the meat of the error
"escalating error to panic"
"contract call failed"
"caught error from function"
"escalating error to panic"
"Unauthorized function call for address"

Great to see this being worked on, thank you! 😃

I have posted that example on twitter in Tomer's thread. Thank you again for your reply.

The task becomes very challenging if you are trying to do cross-contract calls. I understand a bit how that works (I helped polish the doc on that part during the last bounty) and once you get how to call another contract from yours, the next challenge becomes: how to read these errors.

Here is an example on my project. I am calling Soroban Domains to register a domain. If I deliberately change that line and use a non valid TLD (these 3 bytes write xlm)

https://github.com/tupui/soroban-versioning/blob/828bf95846fcdb5fa884ca5c7bb6f3ca73986017/contracts/versioning/src/lib.rs#L209

Then it will result in this panic.

There are a few things here. First the stacktrace is too long 😅 It's showing me too much of what happened with previous calls I made running the test suite. It took me a while, too long I care to admit, to actually understand that and it was not relevant to my issue. Removing all that, we are left with 10 items, still a bit too long and there is quite some repetition due to this escalation in the stack. What you might eventually start to notice is the repetition of Error(Contract, #4)]. It took me a while to also get what this was: the error code thrown by Soroban Domains contract itself. But what is this 4. Here you have to find the source code to finally get to it (can also not be that obvious to find):

https://github.com/Creit-Tech/sorobandomains-sc/blob/main/contracts/registry/src/errors.rs

And here we have it in the enum: UnsupportedTLD = 4. (Getting the correct parameters is another story in itself 😅 same with making tests.)

I am not sure how all that is possible, but if there was a way to resurface better the meaning of error codes, that would be really helpful. Then, adding colors as @kalepail suggest could be super helpful to separate sections. This could also be accomplished by splitting a bit more the output of the trace. I guess in some cases you want this super verbose output and my case is "too simple". But that's the thing to me simple cases like these should be simple to debug and for now it's hard.

Hope that helps 😃

@tupui Thank you for sharing more details and an example, this is helpful as we think about how to restructure this data.

Here you have to find the source code to finally get to it (can also not be that obvious to find):

https://github.com/Creit-Tech/sorobandomains-sc/blob/main/contracts/registry/src/errors.rs

And here we have it in the enum: UnsupportedTLD = 4.

Fyi if you have the .wasm for the contract, or you know it's address on chain, you can lookup the error using the specification without the source.

$ stellar contract info interface --network testnet --id CADDH3WW3EHDEUY4HIQUAZHRPCFQFL4MZIEZBFUIIHJAXZNLQWVC6DV4
...
pub enum ContractErrors {
    UnexpectedError = 0,
    AlreadyStarted = 1,
    RecordAlreadyExist = 2,
    InvalidDuration = 3,
    UnsupportedTLD = 4,
    RecordDoesntExist = 5,
    InvalidDomain = 6,
    ExpiredDomain = 7,
    InvalidParent = 8,
    OutdatedSub = 9,
    InvalidTransfer = 10,
    InvalidOfferAmount = 11,
    OutdatedOffer = 12,
    OfferDoesntExist = 13,
}

@Ifropc Maybe we should add another sub-command to contract info, such as contract info errors, that just outputs a json mapping of errors to error codes 🤔

Thanks, I did not know that command 👍 That will help in such cases. Might be more tricky if the underlying contract does not properly validate inputs and would break (I did not check, so just talking hypothetically here.)

I am not sure if this is the right place, but I found another interesting case with some obscure error message.

If you are using storage, at compile time it does not tell you if you are using the correct type to store and update values.

e.g. with this structure

#[contracttype]
pub struct Proposal {
    ...
}

#[contracttype]
pub struct Dao {
    pub proposals: Vec<Proposal>,
}

#[contracttype]
pub enum ProjectKey {
    ...
    DaoTotalProposals(Bytes),
}

I was wrongly updating an entry of ProjectKey::Dao with Proposal although I had first set the value to be Dao

env.storage()
    .persistent()
    .set(&ProjectKey::Dao(project_key, page), &proposal)

And this gives this error

differing host map and output slice lengths when unpacking map to slice

(Additionally it was also not pointing directly to the problematic line but I could find that using RustRover's debugger.)

This bugged me for a while. Here I got some luck with Stella 😅

Understanding the Storage Get Error

This specific error occurs when trying to retrieve data from storage where there's a mismatch between the data structure you're trying to deserialize into and the actual data stored.

Common Causes

  1. Data Type Mismatch
// If you stored data as one type
#[derive(Clone)]
#[contracttype]
pub struct OldDao {
    field1: String,
    field2: i32,
}

// But trying to retrieve as another type
#[derive(Clone)]
#[contracttype]
pub struct NewDao {
    field1: String,
    field2: i32,
    field3: Vec<String>, // Added field
}

How to Fix

  1. Verify Your Data Structure
#[derive(Clone)]
#[contracttype]
pub struct Dao {
    // Make sure this matches exactly what was stored
    // Including all fields and their types
}

// When retrieving
let dao: Dao = env.storage().persistent()
    .get(&DataKey::Dao(project_key, page))
    .unwrap_or_else(|| panic!("Not found"));
  1. Check if Data Exists
// Safe retrieval with error handling
if let Some(dao) = env.storage().persistent().get(&DataKey::Dao(project_key, page)) {
    // Data exists and matches the type
} else {
    // Handle case where data doesn't exist
}

Best Practices

  1. Always keep track of your contract's data structure versions
  2. When updating contracts, ensure compatibility with existing stored data
  3. Consider implementing migration strategies for data structure changes

If the error persists, try:

  • Checking the exact type definition used when the data was stored
  • Verifying the storage key structure matches what was used for storing
  • Using debug prints to confirm the data exists in storage

I can see how that error message didn't point at the issue at all. This is, in general, the issue with errors within host functions, they have no context where they're being used and for what. So in this case that host function was being used for custom type struct unpacking. The context about that is in the sdk, but the error is being raised and the contract is being terminated before returning back to the contract where the context is.

That's cool to see Stella bot could recognise the issue.
