Reproduction steps

Hi,

I am working with commit ID 66de0ad. While publishing the coverage report, a null pointer exception is seen:

Expected Results

Coverage report gets generated and published successfully

Actual Results

Null pointer exception is seen

Anything else?

No response

Looks like the coverage report I was using was generated with "-summary-only" option due to which segments were not getting added to the json. Removing the flag fixed the issue for me.
