github actions cant find fastlane folder

Question

I'm trying to deploy my ionic capacitor app to google play using github actions and fastlane.

This is my workflow:

On the Build & deploy Android release it can't find my fastlane folder with the fastlane files. I get this error:

`
[21:03:05]: Sending anonymous analytics information
[21:03:05]: Learn more at https://docs.fastlane.tools/#metrics
[21:03:05]: No personal or sensitive data is sent.
[21:03:05]: You can disable this by adding `opt_out_usage` at the top of your Fastfile
[21:03:05]: Could not find fastlane in current directory. Make sure to have your fastlane         configuration files inside a folder called "fastlane". Would you like to set fastlane up?
`

On the step before i run a command to list the files in the fastlane folder if it exists and this is what i get from that command.

Files in fastlane folder: total 16

-rw-r--r-- 1 runner docker  223 Mar 27 20:58 Appfile
-rw-r--r-- 1 runner docker  517 Mar 27 20:58 Matchfile
-rw-r--r-- 1 runner docker 4416 Mar 27 20:58 fastfile

Clearly all the files is in place and they are placed in the fastlane folder just as they are supposed to. So how come fastlane is still complaining about that it can't find the fastlane files?

Here is my fastfile if that helps:

I have tried a lot of different things but i can't make it find the files....

Now i get this error: Your bundle only supports platforms ["x64-mingw-ucrt"] but your local platform is x86_64-linux. Add the current platform to the lockfile with bundle lock --add-platform x86_64-linux and try again.

Which was the one i managed to solve using this bundle part:

 - name: Add current platform to Bundler lockfile
      run: |
      bundle lock --add-platform ruby
      bundle lock --add-platform x86_64-linux
