bitbucketcloud: cel expression parsing error #2335
Description
Using a standard push event emitted by a bitbucket cloud webhook, the openshift-pipelines/pipelines-as-code-controller-* (version: v0.37.3) pod logs a parsing error even when using the most simple CEL expression imaginable.
In .tekton/cd-pipeline-dev.yaml I configured a PipelineRun (that worked when not using cel expressions) that looked like this:
apiVersion: tekton.dev/v1
kind: PipelineRun
metadata:
name: cd-pipeline-dev
annotations:
pipelinesascode.tekton.dev/on-cel-expression: |
true
... (rest truncated)
The error that is thrown in the mentioned pod:
{"level":"error","ts":"2025-11-26T09:32:54.671Z","logger":"pipelinesascode","caller":"matcher/annotation_matcher.go:282","msg":"there was an error evaluating the CEL expression, skipping: json: cannot unmarshal string into Go value of type map[string]interface {}","commit":"10dee4fce84b750d7597e61d78a420101ab36d78","provider":"bitbucket-cloud","event-id":"","event-sha":"2d131ec316899a34bb78e00fd7f7bb931112d8da","event-type":"push","source-repo-url":"https://bitbucket.org/walter-group/tkn-demo-go-bb","target-branch":"test-cel","namespace":"phx","stacktrace":"github.com/openshift-pipelines/pipelines-as-code/pkg/matcher.MatchPipelinerunByAnnotation\n\t/go/src/github.com/openshift-pipelines/pipelines-as-code/pkg/matcher/annotation_matcher.go:282\ngithub.com/openshift-pipelines/pipelines-as-code/pkg/pipelineascode.(*PacRun).getPipelineRunsFromRepo\n\t/go/src/github.com/openshift-pipelines/pipelines-as-code/pkg/pipelineascode/match.go:282\ngithub.com/openshift-pipelines/pipelines-as-code/pkg/pipelineascode.(*PacRun).matchRepoPR\n\t/go/src/github.com/openshift-pipelines/pipelines-as-code/pkg/pipelineascode/match.go:38\ngithub.com/openshift-pipelines/pipelines-as-code/pkg/pipelineascode.(*PacRun).Run\n\t/go/src/github.com/openshift-pipelines/pipelines-as-code/pkg/pipelineascode/pipelineascode.go:58\ngithub.com/openshift-pipelines/pipelines-as-code/pkg/adapter.(*sinker).processEvent\n\t/go/src/github.com/openshift-pipelines/pipelines-as-code/pkg/adapter/sinker.go:75\ngithub.com/openshift-pipelines/pipelines-as-code/pkg/adapter.(*listener).Start.listener.handleEvent.func2.1\n\t/go/src/github.com/openshift-pipelines/pipelines-as-code/pkg/adapter/adapter.go:206"}
It seems that cel expression were either never working or are at least broken for the mentioned version of PAC and current version of Bitbucket cloud.
Appreciating a fix!
