Broken pipe when trying to upload apk to Maestro Cloud

[joknjokn]

If you are looking for help, please confirm the following...

• I confirm I have searched the Docs, Codemagic Sample Projects, and GitHub Discussions.
• I confirm the software versions on my local computer match the ones in CI environment (e.g. Xcode version, Gradle version). See here
• I confirm I am able to do a fresh clone of the repository and build the project on my local computer.

Which mobile framework are you using?

Flutter (Dart)

Steps to reproduce

1. I've setup a workflow with the Codemagic tutorial scripts for using Maestro Cloud
2. In post-publishing, everything looks good - Maestro has been installed, builds succeeded,
3. but when "maestro cloud" then tries to upload the .apk to Maestro Cloud, I get "Broken pipe"

What can cause this? Any settings I can tweak somehow, or ideas for debugging?

Expected results

Expected the upload to succeed

Actual results

Error: Uploading Flow(s)...

Hello @joknjokn, regarding the Maestro Key you specified under Teams > Global env vars, please be aware that this can only be utilized in the yaml configuration.

As you are currently using the workflow editor, kindly include the env var in your editor settings and proceed with running the build. Please keep us updated on the outcome.

@himesh-cm Thanks. I added it to Teams->Global env vars, because your Maestro-tutorial mentioned to add the 'maestro' variable group. But I guess that's not necessary then. I'll try with env-vars in the build workflow instead, thanks!

@himesh-cm Uploading works now.

Maestro doesn't run the app apparently, so that part doesn't work for us yet - but I assume that's not a Codemagic issue.

Thank you for the help - maybe update your guide to include instructions about how to use Maestro with Build Workflow!
