Sometimes Power BI returns the error "The key didn't match any rows in the table" when the dataset refreshes.
There are a couple of reasons this could happen, in this article we will show you the common reasons and solutions.
Incorrect Connection Information
Cause: Sometimes this happens if you have the server and database backward or have entered the incorrect schema for the role.
Resolution: Double-check your parameters and authentication match.
Note: Be sure that the Schema name is open (all lower-case).
Out of Date tyGraph Model
Cause: At tyGraph, we maintain at least one generation of data model back from the current. But if you've missed two updates there is a chance the old tables needed for your out-of-date tyGraph Model won't exist. If this has happened you will also get the "The key didn't match any rows in the table" error.
Resolution: If you're running the latest version and have the correct connection please start a ticket with us or email firstname.lastname@example.org
