Description
I’m using bazel 3.5.0 to generate code coverage.dat files for my C++ build. The coverage.dat files seem to be in lcov format.
I’m using the bash uploader to upload these files, and it appears to work. However, when I try to view the results in the codecov.io UI, I see a generic message like “There was an error processing coverage reports.”, but it doesn’t tell me what the error was, nor provide any way to debug.

An internal Google thing called “kokoro”.

Additional Information
This appears to work sometimes. As you can from the commits in this PR Codecov, some of them do process the code coverage info. I’ve no idea why it fails sometimes, and I have no idea how to debug this or where to look for errors.
