Cannot deploy app

[beneuto]

Describe the issue

Creating a Streamlit app from the template and using the deploy command provided in the UI results in error.

Steps to reproduce the behavior

1. Create an app in the Databricks UI using the Streamlit Data template
2. Open the new app configuration and copy the CLI command from the "Deploy to Databricks Apps Section"
3. I have prefixed the source path with another "/" as is the norm when running from Windows but the same result occurs with or without.
4. Run the command (I am using VS Code on Windows 10 with Databricks extension and CLI installed):

$ databricks apps deploy test-app --source-code-path //Workspace/Users/me@mine/databricks_apps/test-app_2025_04_09-04_59/streamlit-data-app --debug

Expected Behavior

App should be deployed

Actual Behavior

Fails with error message claiming Workspace path is invalid.

OS and CLI version

Windows 10 CLI v0.246.0

The path provided in --source-code-path is remote Workspace path so no need for double slashes. But since you mentioned the same error happens with single slash can you double check that the path you use exists and that the user you authenticated with in CLI and the user owning the path are the same?

[beneuto]

I am using the paths provided in the UI for the app and have no issue with authentication with other commands. I have also tried dozens of path variations that seemed reasonably possible but get the same error every time.

I've found that if I first deploy from the UI then I can redeploy from the same location in VS Code by omitting the path altogether.

Following is an annotated transcript of a VS Code session: ` *** CREATE A CUSTOM APP IN THE DATABRICKS UI

Thanks for sharing. Are you using Git Bash, correct? Is putting the path into single quotes work for you, something like this

databricks apps deploy test-app --source-code-path `/Workspace/Users/[email protected]/test-app`

[beneuto]

Bash yes but no, had tried quotes earlier along with many other likely options.

(.venv)

$ databricks apps deploy test-app --source-code-path '/Workspace/Users/[email protected]/test-app'

This issue came up in #2851 internally just now.

The path conversion seems to be done by your shell. Can you try setting MSYS_NO_PATHCONV=1?

[beneuto]

Can you try setting MSYS_NO_PATHCONV=1?

That fixed it, thanks.

[pietern]

Excellent, thanks for confirming.
