What’s happening?
Customers experience an intermittent error message stating "Network error when using Patch function" while using a Power App to access data from a SharePoint Online list, even though the app does not directly use the Patch function.


Reason:
The status code '0' typically indicates a network-level interruption, such as temporary connectivity issues, proxy/firewall interference, or client-side disruptions where the request fails before reaching the server. This may also arise from mismatches in field types, missing or invalid data, incorrect syntax, or settings in SharePoint lists.


Resolution:

  1. Field Type Mismatch: Ensure that the field types in the Power App match those in the SharePoint data source. For example, if patching a People field in SharePoint, ensure it corresponds correctly with the field type in the app.
  2. Missing or Invalid Data: Verify that all required fields have valid data before submitting the form. For instance, ensure that the 'Mail' column of each record is populated.
  3. Incorrect Patch Syntax: Check the syntax used for patching complex SharePoint fields. Ensure that the correct format is being utilized.
  4. Use of Monitor Tool: If this persists, consider using the Monitor tool in Power Apps to run the app in the designer and recreate the bug. This will allow for a review of the trace to help identify the issue.
  5. Update SharePoint List Settings:
  6. Navigate to List Settings > Advanced settings.
  7. Set "Allow Management of Content Types" to Yes (default is No).
  8. Go back to settings and ensure the Column title is set to remove the required information to No.
  9. Check Column Types and Constraints: Ensure that the column types and constraints in the SharePoint list match those in the Power App.
If the issue continues to occur sporadically, it may be necessary to capture new logs for further analysis.
