action not running sometimes

[santhosh1329]

The labelling action is configured for my workflow, and it is working perfectly fine for almost 2 and a half months, but it is causing trouble. The problem is here it is not triggering for some pull requests, and it get resolved automatically after sometime. There is no pattern as it is happening for random pull request's, i need to quickly act upon this as this was a required status check in my workflow.Please help me out in this case :)
