Database error

I noticed after updating to 9.2 I am getting the following database error when refreshing database entities;
An exception occurred while executing ‘ALTER TABLE GroupSignups ADD CONSTRAINT FK_D6CC4ECBFD71026C FOREIGN KEY (uID) REFERENCES Users (uID) ON DELETE SET NULL’: SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (juwatero_juwater.#sql-alter-357911-201bf57, CONSTRAINT FK_D6CC4ECBFD71026C FOREIGN KEY (uID) REFERENCES Users (uID) ON DELETE SET NULL)

it appears to be a user error or a user can’t be found in the database. Any ideas on how to correct the error. I also get the following error when the admin tries to get “work waiting for me” from the daseboard; Exception Occurred: /home/juwatero/public_html/updates/concrete-cms-9.2.0/concrete/vendor/doctrine/orm/lib/Doctrine/ORM/Exception/MissingIdentifierField.php:13 The identifier uID is missing for a query of Concrete\Core\Entity\User\User (0)

@mmaheux Yeah that is strange - do you know if you did any database surgery on this that might’ve neglected to delete a user from a set?

You might see if you can see what uID it’s looking for and where. Looks like it might be trying to delete a user set maybe?
