I’ve checked my JSON with jsonlint and all of the submissions are being created from the same program so I don’t think it’s a formatting error. I’ve not run out of credits on the dashboard and there are only 23 service locations in the submission (other submissions have over 30 and they work OK).
Would you please check the submitted JSON that the services do not contain invalid service locations - in your case they seem to be lat=0 lon=0. We definitely have to improve the error message here, of course and the original problem is also fixed now.
If this was not the issue you meant, I would need the submitted JSON (e.g. send via private message).
