User field `authData` cannot be deleted

New Issue Checklist

• I am not disclosing a vulnerability.
• I am not just asking a question.
• I have searched through existing issues.
• I can reproduce the issue with the latest versions of Parse Server and Parse Dashboard.

Issue Description

Trying to delete the authData field in the _User collection fails with error:

This authentication method is unsupported.

Steps to reproduce

1. Find user with a populated authData field
2. Select cell
3. Hit delete button

Actual Outcome

Error message appears, field value is not deleted.

Expected Outcome

Field value should be deleted.

Note

It also does not work to only select a specific auth provider in the authData field and delete on that provider entry, e.g. "facebook: { ... }" or "apple: { ... }". The result appears correctly in the cell with the authData field updated to {}, even showing a success pop-up. But after refreshing the data browser, the auth data is still there.

Environment

Dashboard

• Parse Dashboard version: 3.2.1

Start in the Data Browser by reproducing deletion of the _User authData field and compare deleting the whole field with deleting a provider entry such as facebook or apple. Verify the fix against the reported error, the refreshed cell value, and the Parse Dashboard 3.2.1 behavior described in the issue.
