Generic “Upload failed” error on CSV import and manual add

[amb-ines]

Can we access your project?

• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

The Manage Data tool cannot add data to my Firestore collections in FlutterFlow. Both CSV import and manual “Add Document” fail—even with a brand-new collection and a 1-row UTF-8 CSV using only two String fields.

Expected Behavior

The CSV import should successfully validate and insert records when:

• Headers match collection field names.
• File is UTF-8 CSV with Comma separator and default text delimiter.
• Field types align (strings only in the minimal test).
• Manual Add Document should create a document when valid values are entered.
• Any validation errors should be surfaced with specific, actionable messages (e.g., row/column and reason), not a generic “Upload failed.”

Steps to Reproduce

1. Open Manage Data in FlutterFlow from the Firestore collections panel.
2. Locate the directory collection (or create a new test collection).
3. Click Upload CSV.
4. Select a simple 1-row CSV file, for example:
   agency_id,agency_name
   OPRET,OPRET - Metro

• CSV is UTF-8 encoded.
• Separator = Comma.
• Text Delimiter = Default.

5. Click Upload CSV to confirm.
6. Observe: import fails with the message “Upload failed. Please try again.”
7. As a second test, click Add Document in the same collection.
8. Enter the following values manually:
   agency_id = OPRET
   agency_name = OPRET - Metro
9. Click Save.
10. Observe: manual document creation also fails (record is not saved, and an error toast appears).
