Hi, can you tell us a little bit more about what is not working and what you are expecting here? We do not support coverage for patrol build IIRC. Maybe it can be feature request but leave more details to the description and what you want to achieve here.

[iammofidul]

We want detailed code coverage result from browserstack patrol test report which is currently not working .
We are getting 404 error with message for this curl --location 'https://api-cloud.browserstack.com/app-automate/espresso/v2/builds/buildId/sessions/sessionId/coverage' \

<?xml version="1.0" encoding="UTF-8"?>

What do you mean by IIRC? ,Patrol code coverage is not supported on Browser stack app automate ?
