I can confirm this is not working as expected and this mainly seems to be a serialization issue:

To see a stacktrace of where the error is coming from, set the var Debug = true in codec/types/compat.go

The most relevant part of the error is:
"XXX_unrecognized:[]}, this is likely because amino is being used directly (instead of codec.LegacyAmino which is preferred) or UnpackInterfacesMessage is not defined for some type which contains a protobuf Any either directly or via one of its members. "

The feegrant and revoke actually are successful transactions that land on chain. The logging in node seems to be the issue on my end

[liamsi]

Hmm, yeah but somewhere the JSON can't be (de-)serialized (hence node is reporting an error):

{
  "result": "RPC client error: sendRequest failed: http status 200 OK unmarshaling response: EOF"
}

So while the transactions seem to work the JSON result is broken.

Given that @vgonkivs tested it before in #3304 (comment), I assume that one of the changes/commits that came after the testing somehow broke sth.

[vgonkivs]

It's not working for me too on the latest main.

[vgonkivs]

seems it panics after marshaling TX

Error: json: error calling MarshalJSON for type *types.Any: unknown message type ""

[jcstein]

I assume that one of the changes/commits that came after the testing somehow broke sth.

Yep! I can confirm that testing this on the PR itself results in successful result

Semantic version: v0.13.2-22-g9f5f4534 (log)

1. log of grant-fee, with no errors in the light node's logs
2. log of revoke-grant-fee, with no errors in the light node's logs

[liamsi]

If the change that led to this has nothing to do with the feegrant PR, it could be that more tx or other responses can't be unmarshalled right now. I think it would be good if API responses would be tested.
