We have a CI pipeline triggered by GitHub Pull Request webhook events that runs functional tests for 14 connectors. We need <+trigger.changedFiles> to be populated at pipeline runtime to conditionally run GitClone steps and functional tests only for connectors whose source files were changed in the PR. Currently, <+trigger.changedFiles> resolves to null at pipeline execution time for PR-based triggers, even though the trigger fires correctly and changedFiles works as a gate condition. Support confirmed this expression is only supported for push-based triggers under the PIPE_TRIGGER_CHANGED_FILES_EXPRESSION flag. We'd like this expression to be extended to PR-based webhook triggers as well, consistent with how it already works for push events. Without this, we're forced to either run the full test suite on every PR across all 14 connectors (wasteful and slow), or maintain a fragile custom script workaround. PR-based triggers are a very common CI pattern, and native support for <+trigger.changedFiles> in this context would benefit a wide range of Harness users.
