### Description

**Background**

1. We use circle CI and run our python tests inside a docker container. Coverage reports are generated inside this docker container.

2. As per [Testing with Docker](https://docs.codecov.io/docs/testing-with-docker), I made sure to mount a filepath where coverage reports will be dumped (here [fairo/.circleci/config.yml at anurag/yml · facebookresearch/fairo · GitHub](https://github.com/facebookresearch/droidlet/blob/anurag/yml/.circleci/config.yml#L136) $PWD is being mounted as /shared and all the coverage reports are dumped here like this [fairo/.circleci/locobot\_tests.sh at anurag/yml · facebookresearch/fairo · GitHub](https://github.com/facebookresearch/droidlet/blob/anurag/yml/.circleci/locobot_tests.sh#L54)).

**Problem**  
All the coverage files generated in step 2 above are named according to the format “test\_\*.xml”. However, when I try to upload them using `bash <(curl -s https://codecov.io/bash) -f "test_*.xml" -F "locobot" ` ([fairo/.circleci/config.yml at anurag/yml · facebookresearch/fairo · GitHub](https://github.com/facebookresearch/droidlet/blob/anurag/yml/.circleci/config.yml#L138)), it looks like the coverage report uploaded to codecov is empty and I just get a message on [codecov.io](http://codecov.io) saying “There was an error processing coverage reports”.

**Questions**

1. What is the exact command that the bash uploader runs to generate the coverage xml? How can I look at this generated coverage xml?
2. I suspected fixing paths could be an issue (as per [Path Fixing](https://docs.codecov.io/docs/fixing-paths)) since the coverages reports are being generated inside a docker container. But I can’t seem to figure out how to fix this if at all it is a problem (here’s my current solution using fixes in the codecov.yml file that doesn’t work [fairo/codecov.yml at anurag/yml · facebookresearch/fairo · GitHub](https://github.com/facebookresearch/droidlet/blob/anurag/yml/codecov.yml#L2))

@anuragprat1k this is really strange. Would you e able to run the uploader in verbose mode with the `-v` flag? I’d like to see why we didn’t pick up your files.
