CRA is unable to process your return at this time as an error was found with the format of the attached file. The format is invalid as there is no data at line number: Schedule: 100 Page: 001 Line: 0001
I believe your staff sent us an email about this. Fin Notes contain invalid characters (hidden columns etc…). We replied to your staff yesterday with a resolution. Please check with your staff. If that does not resolve the issue. Post back and left me know.
