Bug: QField Sync Plugin Removes Path Segment from URL

[edouardbruelhart]

I've encountered a bug with the QField Sync plugin where it incorrectly handles the base URL for connecting to a self-hosted QFieldCloud instance, served using a custom nginx configuration. Specifically, the plugin is removing the /qfieldcloud/ segment from the URL, which leads to a 404 Not Found error when attempting to authenticate or interact with the API.

Steps to Reproduce:

• Configure the QField Sync plugin with a base URL that includes the /qfieldcloud/ segment, e.g., https://emi-collection.unifr.ch/qfieldcloud/.
• Attempt to perform an action that requires authentication or interaction with the API (e.g., logging in or syncing).
• Observe that the plugin makes requests to URLs without the /qfieldcloud/ segment, e.g., https://emi-collection.unifr.ch/api/v1/auth/login/.

Expected Behavior:

The QField Sync plugin should use the full base URL provided, including all path segments, so that requests are correctly routed to the API endpoints. For example, the URL https://emi-collection.unifr.ch/qfieldcloud/api/v1/auth/login/ should be used instead of https://emi-collection.unifr.ch/api/v1/auth/login/.

Actual Behavior:

The plugin removes the /qfieldcloud/ path segment from the URL, resulting in incorrect requests like https://emi-collection.unifr.ch/api/v1/auth/login/, which leads to 404 Not Found errors.

Additional Information:

I have tested to connect to the instance using a web browser, QField application and directly using curl and confirmed that it works with the /qfieldcloud/ path segment. The issue seems to be specific to how the plugin constructs URLs.

Environment:

• QField Sync Plugin Version: 4.10.1
• QGIS Version: 3.38.2
• Operating System: Ubuntu 22.04
• QFieldCloud URL: https://emi-collection.unifr.ch/qfieldcloud/

Thank you for your attention to this issue. Please let me know if you need any further details or if there is a workaround available.
