/columns API endpoint returns undefined for name, options, and required fields, breaking row insertions via API

Describe the bug:

The /columns endpoint of the Nextcloud Tables API is returning incomplete metadata for all columns in my table. Specifically, every column shows:

"name": undefined
"required": undefined
"options": [] (even for selection fields with options)

As a result, attempts to insert rows via the API consistently fail with HTTP 500 and the message: Could not create row.
This issue occurs even though:
All columns in the GUI are correctly named.
Column types (text, selection, datetime) and options are clearly visible and editable via the UI.
Columns have been made optional and edited to ensure they save correctly.

To Reproduce:

Create a table in Nextcloud Tables with various column types.
Use the /columns API endpoint to inspect column metadata.
Attempt to insert rows via the API using valid column IDs and values.
Observe HTTP 500 errors and incomplete column metadata.

Expected behavior:

The /columns endpoint should return correct names, required flags, and selection options.
Row insertions should succeed if valid data is provided.

Start with inspect-columns.mjs and the /columns endpoint, then trace the row-insertion request that returns “Could not create row.” Compare the endpoint response with the table metadata shown in the GUI. Done means names, required flags, and selection options are returned correctly and valid row insertions no longer fail.
