QC Netfile error: MDR901 Element is Invalid

Hi! I’m trying to Netfile my mom’s return and the CRA one worked but the Revenu QC one says: The MDR901 element is invalid. The value (phone number) in invalid according to it’s data type. The pattern constraint failed. 

 

I tried changing her phone number to the one at her residence vs the one that goes to her room directly but that didn’t work either. Help please!
