### Description I’m trying to make Codecov for monorepo, which has this setup: ```auto ./ ./api ./frontend ``` The API is hosted and CI-managed by Heroku. Due to Heroku’s specifications, the CI flow looks like this: 1. Remove ./frontend 2. Move ./app/\* to ./ (the root dir) 3. Run tests and code coverage there. For Codecov to work, we applied some path fixing: ```yml fixes: - "::api/" ``` This works for the API, but the frontend coverage, which is handled by GitHub Actions, doesn’t appear on Codecov, even though the Action runs OK and the coverage is reported to be uploaded. Instead, we’re receiving this error: ![image](https://canada1.discourse-cdn.com/flex029/uploads/codecov/original/2X/3/3163cad8f986cb5ed382ba4336bd1be3b44da2d1.png) I’m guessing here that the fix `"::api/"` applies to the `frontend` as well and breaks the paths, but I’m not sure. I’ve tried these to no avail: - Rewriting the fixes with RegEx to _not_ rewrite paths that start with “frontend” - Use a granular “/home/runner/work/eve/eve/frontend::frontend/” fix that matches GitHub’s directory structure - Use a different codecov.yml for `api` and `frontend` - Mixing flags and stuff, e.g., ### Commit SHAs `a2263fdbc07de51171dab7febc2ceaf887d0ab34` (private) ### Repository [https://github.com/Eveio/eve](https://github.com/Eveio/eve) (private) ### CI/CD or Build URL [https://github.com/Eveio/eve/runs/1680232543](https://github.com/Eveio/eve/runs/1680232543) (private) ### Uploader Bash uploader. ### Codecov Output ```auto /bin/bash codecov.sh -n -F frontend -Q github-action _____ _ / ____ | | | | | _____ | | ______ _______ | | / _ \ / _` |/ _ \/ __/ _ \ \ / / | |___| (_) | (_| |__/ (_| (_) \ V / \ _____\___ / \ __,_|\___ |\ ___\___ / \_/ Bash-20201231-23d4836 ==> git version 2.29.2 found ==> curl 7.58.0 (x86_64-pc-linux-gnu) libcurl/7.58.0 OpenSSL/1.1.1g zlib/1.2.11 libidn2/2.0.4 libpsl/0.19.1 (+libidn2/2.0.4) nghttp2/1.30.0 librtmp/2.3 Release-Date: 2018-01-24 Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtmp rtsp smb smbs smtp smtps telnet tftp Features: AsynchDNS IDN IPv6 Largefile GSS-API Kerberos SPNEGO NTLM NTLM_WB SSL libz TLS-SRP HTTP2 UnixSockets HTTPS-proxy PSL ==> GitHub Actions detected. -> Issue detecting commit SHA.

@phanan, what happens if you remove the `paths` from the `flag` section of the yaml? ---

@tom Thanks for answering. With that, I’m assuming that I should remove the `-F` flag from codecov command as well? ---
**Author:** ![phanan](https://yyz1.discourse-cdn.com/flex029/user_avatar/community.codecov.com/phanan/32/1460_2.png) [@phanan](https://community.codecov.com/u/phanan)\ **Post date:** [January 12, 2021, 7:19am UTC](https://community.codecov.com/t/cant-get-codecov-to-work-with-monorepo/2462/4 "2021-01-12T07:19:56Z")
@tom So I have removed everything flag from the config and build commands. My `codecov.yml` is now a minimal ```auto fixes: - "::api/" ``` The results are as follow: - The _API_ coverage (processed and uploaded by Heroku) still works fine - The _frontend_ coverage (processed and uploaded by GitHub) shows up in Codecov with correct metrics, but all paths are prefixed by `api/` (I guess due to the path fixing) and are broken: - As you can see, there are two separated reports. My ultimate goal (if possible) is to merge them into one (and have it reported by Codecov bot in GitHub as one). Basically this is the “reversed” version of where we initially started (having no `codecov.yml`)—both reports appeared separately, `frontend` worked fine, `api` showed up with broken paths. What do you reckon should be the next thing to try? ---

Update: I’ve modified the path fix to be a regex that negates `frontend`, like this: ```auto fixes: - "^(?!frontend)::api/" ``` and the coverages now correctly show up in Codecov, but still as two separate reports. What can be done to merge them into one, preferably properly flagged? Edit: I’ve also tried uploading each coverage with the corresponding flag (without specifying them in `codecod.yml`) e.g. `bash <(curl -s https://codecov.io/bash) -F frontend` and `bash <(curl -s https://codecov.io/bash) -F api`. This still doesn’t work as expected. Instead, it goes like this: 1. Codecov bot initially displays both `api` and `frontend` statistics 2. Upon `frontend` finishes coverage reporting, the statistics are replaced with `frontend` specifics 3. Upon `api` finishes coverage reporting (as it takes longer than `frontend`), the (frontend) statistics are replaced by `api` specifics. What I’m looking for is essentially a report for _both of them_. ---

Hi @phanan, I’m a little confused about your question. > the coverages now correctly show up in Codecov, but still as two separate reports Can you share a link or screenshot of this happening and explain what you would want it to look like instead? ---
**Author:** ![phanan](https://yyz1.discourse-cdn.com/flex029/user_avatar/community.codecov.com/phanan/32/1460_2.png) [@phanan](https://community.codecov.com/u/phanan)\ **Post date:** [January 12, 2021, 2:25pm UTC](https://community.codecov.com/t/cant-get-codecov-to-work-with-monorepo/2462/7 "2021-01-12T14:25:52Z")
Sure @tom. ![image](https://canada1.discourse-cdn.com/flex029/uploads/codecov/original/2X/f/f024888d74ec8764fa5f2932b2ae72ec37ca67af.png) You’ll notice that there’s only one flag (`api`) and its statistics are shown here, even though there are actually two coverages generated in this commit—one by Heroku, and one by GitHub Actions. The reason why it’s `api` is that, as I explained above, Heroku’s CI finished _later_ and replaced the previous `frontend` statistics. I’d like both coverages `api` and `frontend` merged and shown here instead. ---
**Author:** ![phanan](https://yyz1.discourse-cdn.com/flex029/user_avatar/community.codecov.com/phanan/32/1460_2.png) [@phanan](https://community.codecov.com/u/phanan)\ **Post date:** [January 12, 2021, 2:34pm UTC](https://community.codecov.com/t/cant-get-codecov-to-work-with-monorepo/2462/8 "2021-01-12T14:34:09Z")
To add more to my previous answer: After GitHub Actions finishes its `frontend` run and uploads the coverage, I can follow the uploaded link and see the coverage on Codecov: ![image](https://canada1.discourse-cdn.com/flex029/uploads/codecov/original/2X/5/5cfe5092529441d9fcbfcf56ed88236f1ae40b8c.png) A little while later, Heroku finishes its `api` run, and I can see its coverage as well (I’m sorry I can’ upload another image due to the forum’s limitation for new users, but replace `frontend/src` from the image above with `api` and you’ll have it.) These reports are, however, separate from each other, even though they’re initialized from the same commit. ---

That’s a great catch, thanks @tom! Indeed, after setting `fetch-depth` to 2, the commits are fixed and _both_ flags show up in GitHub. However, the “Continue to review full report at Codecov” link now yields a server error: ![image](https://canada1.discourse-cdn.com/flex029/uploads/codecov/original/2X/8/8f26106e7d95573f26933b092144621d831bb11d.jpeg) Is it because I’m doing something funny with the config or…? ---

FWIW, in following up on my thread on tags, I also had a few minutes where the PR view would come back with a 500 page. And then it would be just fine.
