Cause:
This error is just a temporary error on the Dash's end due to the temporary database being full at the time that user are submitting the records to Dash.
This will be resolved by itself within a short period of time.
Fix:
Usually, resubmitting the transaction, even without making any adjustments should allow the property to submit successfully.
Additional Considerations:
If the same error occurs repeatedly for the same property record, there's another factor causing this submission failure. Please contact or submit directly a ticket to Anywhere Real Estate Inc. and their support team will look into it immediately.
