Error processing coverage reports with GitHub actions


The reports are successfully uploaded from GitHub actions, but on codecov side I always receive “There was an error processing coverage reports.” without any additional info.

I was having the same issue – downgrading from codecov/codecov-action@v2 to codecov/codecov-action@v1 worked for me (suggesting it’s maybe a bug with the action?).

Note: codecov-action@v1 is set to be deprecated Feb 1, 2022

Also having this issue. Started experiencing it after the Github Actions we’re down yesterday (2021-10-05) for a few hours.

Worked around this for now by using the bash uploader ( [Deprecating] Bash uploader ) though it’s marked deprecated on February 1st, 2022.

I was about to file the same bug report. This is happening with codecov/codecov-action@v2.1.0. The log says that the report has been uploaded successfully. But I noticed that the pushes on the web UI don’t have any data attached and show up as 0%. There’s also no PR statuses or comments anymore. This has been happening for 1-2 days: Code coverage done right.. On that page, it’s very clear when the reports stopped showing up but here’s the last “covered” commit Code coverage done right. and here’s the next one showing up with 0% Code coverage done right..

Weird… Looking at the last processed report, I see that the files at the beginning are separated by a new line:

<<<<<< network
# path=./coverage.xml
<?xml version="1.0" ?>
<coverage version="5.5" timestamp="1633414049761" lines-valid="9843" lines-covered="9600" line-rate="0.9753" branches-valid="3199" branches-covered="2997" branch-rate="0.9369" complexity="0">

But the first “bad” report has all of the file names concatenated with even no whitespace in between:

...tests/test_worker.pytools/bench-asyncio-write.pytools/check_changes.pytools/check_sum.pytools/cleanup_changes.pytools/drop_merged_branches.shtools/gen.pyvendor/http-parser<<<<<< network
# path=./coverage.xml
<?xml version="1.0" ?>
<coverage branch-rate="0.9442" branches-covered="2994" branches-valid="3171" complexity="0" line-rate="0.9768" lines-covered="9592" lines-valid="9820" timestamp="1633473294378" version="5.5">

Interestingly, when the XML section starts, it’s multilined.

Comparing the workflows that uploaded the reports ([] pre-commit autoupdate (#6039) · aio-libs/aiohttp@ed49e88 · GitHub and Add custom RST roles extlinks to the docs setup (#6045) · aio-libs/aiohttp@13c26be · GitHub), the only difference I’ve noticed was that the bad reports were uploaded with a slightly newer version of the underlying uploader. This must be where the bug is coming from:

UPD: Looks like they’ve recently allowed specifying the version of the uploader in the action inputs: Allow specifying version of Codecov uploader · codecov/codecov-action@72dfd47 · GitHub.
I’ll try it out later and will report back.

UPD2: The bug seems to be in this line Comparing v0.1.3...v0.1.4 · codecov/uploader · GitHub.

UPD3: I’ve filed an upstream bug at [v0.1.4 regression] The file list in the uploaded reports is squashed · Issue #411 · codecov/uploader · GitHub.

UPD4: This has been fixed in the new release v0.1.5 (via fix: 🐛 Preserve LF in the report file names list by webknjaz · Pull Request #413 · codecov/uploader · GitHub) and I’ve confirmed that restarting the old GHA jobs will get this problem fixed since they’ll pull in the new uploader version.


Thank you again for the report, @webknjaz and sorry to all those affected. If your version of the uploader says it is 0.1.4, this is the issue. The corrected version of 0.1.5 has indeed been pushed .
