An Azure relational database service.
Welcome to Microsoft Q&A and thanks for your query.
This export error seems to be related to a known issue wherein automated export doesn’t handle databases where elastic jobs were configured. You can create a database copy using
https://learn.microsoft.com/en-us/azure/azure-sql/database/database-copy?tabs=azure-powershell
Then, remove the elastic job related objects "jobs_internal.*" from the copied database, Export the database and then you can delete the copied database.
SQL DB Product team already aware about this limitation and working on improvement.
Please keep us updated on how it goes.
Thank you!
