WireMock.Net TestContainer - Docker Logs contain Template references a helper that cannot be resolved. Helper Linq, only on Github Action

[epDugas]

Using WireMock TestContainers.
I have an integration test that is only failing when executed during a Github Action. I do not experience this issue locally. The docker log message that is related to the test failure is:

Template references a helper that cannot be resolved. Helper \u0027Linq\u0027

The handlebar template string I am using is:

"{{Linq request.bodyAsJson 'it.requests.Count()'}}"

The github test runner OS is:
Ubuntu
24.04.1

This test was working as of yesterday during the Github Workflow, and seems to have broke suddenly.
Any help/guidance would be greatly appreciated.

Apologies, I should have reviewed recent releases. I see that dynamic linq was disabled. Request suggestion to achieve the same as the above.

"{{Linq request.bodyAsJson 'it.requests.Count()'}}"

which is to get the count of a json array contained in a property named "requests" in the request.bodyAsJson.

I submitted a PR at Handlebars.Net.Helpers to add an Enumerable.Count helper.
I looked at adding a custom helper with HandlebarsRegistrationCallback, but did not see a "hook" to add this to the WireMock.Net TestContainer. builder.

@epDugas
Thank you. I left a review comment at, Handlebars-Net/Handlebars.Net.Helpers#113.
Can you take a look?

[StefH]

BTW I was thinking, can't you use the length ?

In handlebars.js, this does seem tot work:

Also works in Handlebars.Net

Thanks @StefH . I tried various things and didn't have any luck. Just tried the following template string again just to verify, and didn't have any luck (the result was null). Just some additional info, I am using this in a static mapping file:

{{request.bodyAsJson.requests.length}}

Request:

"BodyAsJson": {
  "requests": [
    {
      "code": "3881",
      "value": "updatedValue"
    }
   ]
},

I've just released NuGet 1.7.1 which includes your handlebars update.

And later today, I'll also release new Docker version.

Docker images 1.7.1 are available.

Confirmed, closing.
