Received this efile error message in T2 CIF:

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

Does anyone know how to fix this? Thanks.

@sunnywong

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.

Thanks Steven for your quick response.

We found the invalid characters are the bullet characters in Fin Notes. Everything went well after we removed all the bullets.
