Unable to add multiple fields at once without save

I think this is likely related to the same issue in this bug: https://www.drupal.org/project/custom_field/issues/3442408 🐛 Max length storage/widget settings out of sync. Needs review so please apply that patch and report back if this issue is also resolved.

-Unfortunately still the same issue, even I applied #10 patch from advised link. I have added like 6-7 so I thought the problem was resolved at first but tried to add 8th one and all got removed :(

Are there any errors in the logs or console errors related to ajax? This is odd...

Can you click the "set default value" widget to expose the default values form when you trigger the error to see if theres some sort of hidden validation going on there? I just added like 15 fields with no issues so something is a bit different with your settings perhaps.

I think it was caused by me.

Problem : I always needed to override the machine-readable name. But I wanted to be very fast so once I added some machine-readable name I immediately clicked on Add another button. However it seems I need to click outside of form first so Ajax will load it and then I can click "Add another".

Here is picture where it is shown that I am still typing inside the form and in case I click Add another button it fails. So first I need to click outside and then continue.
