I received this new error message from the XML deposit via POST:

Record not processed because citation with key PhysRevX.15.011009Cc1R1 was simultaneously updated in another deposit.

Is this a new message related to the Duplicate key error we used to receive or does pertain to something else?

Thanks

Hi @mklem ,

Thanks for flagging this. It is the same underlying cause. We re-wrote the error message to hopefully eliminate some confusion, as the previous error message was less clear than this one. As a result of our database migration late last year, we are processing submissions more quickly, which we believe is the likely cause of this error and others you are reporting.

Thank you,  
Isaac
