500 Server Error uploading to Codecov for a Julia project

The last few times I’ve tried to run the build task for my project, I’ve run into the following error:

[ Info: Submitting data to Codecov...

    ERROR: HTTP.ExceptionRequest.StatusError(500, "POST", "/upload/v2?&branch=main&pull_request=false&service=travis-org&job=764475148&build=11.1&commit=69d0a54203b7fdffda143bf37b63c6916d87d66a&slug=aditya-sengupta/SparseTransforms.jl", HTTP.Messages.Response:

    Stacktrace:

Done. Your build exited with 1.

This doesn’t seem to be an error with my code - all tests pass, both locally and on Travis. How should I go about fixing it?

Looks like a Codecov-related rather than Travis-related error.

If you print response headers, too, maybe they’ll have more info on what went wrong.
