This issue persists. Despite the UI problem (get the error using UI interface), I have been able to upload via VSCode … until today, wherein I get the same error in my client terminal. One observation is that it is a very generic and unhelpful error message giving no clue as to the source (client/server? syntax? datatypes? etc.) of the problem. Another aspect is that the schema is at the heart of everything the system does, so the inability to update it acts a serious limitation on development. I am attempting to resolve another issue that requires a schema update
however, I cannot progress with that, and other issues, whilst this problem persists …
