Hi!

I want to use the plugin [bitrise-step-comment-on-github-pull-request/step.yml at master · kvvzr/bitrise-step-comment-on-github-pull-request · GitHub](https://github.com/kvvzr/bitrise-step-comment-on-github-pull-request/blob/master/step.yml) to put a comment in the PR

But all the env related to the PR are empty

echo “$BITRISEIO\_PULL\_REQUEST\_REPOSITORY\_URL”  
echo “$BITRISE\_PULL\_REQUEST”

I tried by setting the trigger\_map

trigger\_map:

- pattern: “\*”  
is\_pull\_request\_allowed: true  
workflow: deploy-dev-android

Are those environment variables available when the build is triggered manually?

Those will only be set when the build is triggered by a Pull Request via webhook or via the API with those values set.
