Retrieve numeric value from jsonpath (if condition)

[rbushri]

Hi,

I have JSON parameters (testResources, prodResources) and I want to use those parameters in my "if condition" the final value should be numeric.

So I tried this:

 {{=inputs.parameters.env=='test'?jsonpath(inputs.parameters.testResources,'$.driver-core'):jsonpath(inputs.parameters.prodResources,'$.driver-core')}}

but I got the error:

 Internal Server Error: templates.general-template templates.general-template.resource.manifest must be a valid yaml

so I tried this condition, and it works fine:

 {{=inputs.parameters.env=='test'?jsonpath(inputs.parameters.testResources,'$.driver-core'):4}}

so my question is what did I do wrong?

The WF yml:

              {

                  "driver-core": 2,
                  "driver-memory": "4g",
                  "executor-pool": "main",
