Text field with a link to a file, the link doesn't work

Steps to reproduce

1. Present table with a text field
2. Create a new data record: Click the 'Create row' button
3. In the text field, use the text editor, the button for 'Insert link' and select 'File or folder'. For example, insert the link to an image.
4. Save the new data record
5. Click on the link you have just created

Expected behavior

Depending on the format of the file, all formats that Nextcloud can typically display should be displayed.
Formats that NC cannot display should be offered for download.

Actual behavior

The generated link does not work!
A new tab will be opened in the browser. To display the image in this tab?
Nextcloud generates the following error message: 'The page could not be found on the server or you are not authorized to view it.'
The message is the same for both links.

Here are two examples of the generated links:

1. https://xxxx.yy/IMG_20210515_164908.jpg?fileId=64359
2. https://xxxx.yy/index.php/apps/tables/Photos/2018-gm/wehrdurchfahrt/DSC00297.JPG?fileId=237

The first link refers to an image in the home directory, at the top level.
The second link refers to a file in a subdirectory.

Additional info

No response

Start by reproducing the file-link workflow described in the issue using Tables 0.6.4, then trace how the text editor creates links and how the app resolves fileId links. No source file or test is named in the report. Done means links to files in both the home directory and subdirectories open supported formats or offer unsupported files for download.
