APEX 26.1: ORA-01400 when converting application to Text Messages

APEX 26.1: Error when converting application to Text Messages

Hi,

I am trying to convert an existing application in APEX 26.1 to use Text Messages.

The conversion fails with the following error:

Error Message
1 error has occurred

ORA-20001: call=wwv_flow_imp_shared.create_message, id=[NULL], component=ROW_TEMPLATE3, sqlerrm=ORA-01400: cannot insert NULL into ("APEX_260100"."WWV_FLOW_MESSAGES$"."MESSAGE_TEXT")

It appears that the conversion process calls:

wwv_flow_imp_shared.create_message

for the component ROW_TEMPLATE3, but passes a NULL value for MESSAGE_TEXT.

The application itself is working normally before the conversion. The error only occurs when switching the application to the new Text Messages mechanism.

Has anyone already encountered this in APEX 26.1?

Is there a known issue or patch for this, or is there a way to identify which application component or template attribute is represented by ROW_TEMPLATE3?

I would expect empty translatable attributes to be skipped instead of creating a Text Message with a NULL message text.

Thanks,
Roland
