Unable to Map Course Error Message When Trying to Link to Google Classroom

[aironfield]

I was able to get 4 out of 5 of my classes to link to Google Classroom through the Integration Center this year (I used this feature last year as well).  However, the 5th class I keep getting an error message that says the course cannot be mapped.  Has anyone else experienced this and do you have a solution?

Morning, 

Yes, we are experiencing a similar instance. A common error we're getting is Export failed. Student not found in SIS.
