A slash character in a TriggerBinding value does not work.

[ggallen]

Expected Behavior

Trying to use a label containing a forward slash (/) in a TriggerBinding JSONPath value does not work.

Actual Behavior

The label value is retrieved correctly and the trigger fires.

Steps to Reproduce the Problem

1. Binding for the trigger:

   
   bindings:
   - kind: TriggerBinding
   name: instance
   value: $(body.build.metadata.labels['agogos.redhat.com/instance'])

...

template: spec: params:

• default: mydefault description: Agogos instance name: instance

  2. This content in the `CloudEvent`:

  { "build": { "apiVersion": "agogos.redhat.com/v1alpha1", "kind": "Build", "metadata": { "creationTimestamp": "2023-07-07T21:28:04Z", "finalizers": [ "builds.agogos.redhat.com/finalizer" ], "generateName": "dummy-component-dep-", "generation": 1, "labels": { "agogos.redhat.com/instance": "b8059400-30c9-4010-bdb4-08f0606601ca" }, "name": "dummy-component-dep-n679w", "namespace": "gallen", "resourceVersion": "153135", "uid": "06977b16-9b6b-4edd-9073-e4aa92c1d725" } } }

After escaping the key, I don't get this error.

  - name: instance
    value: $(body.build.metadata.labels['agogos\.redhat\.com\/instance'])
``

I will create a documentation for this.
