Panic when updating code in a callbackFunction

See original GitHub issue

Issue details

I’m using a callbackFunction to create a lambda with the code in a separate file. When I update the code of the lambda and do an update I get the following error:

panic: interface conversion: interface {} is []interface {}, not *schema.Set
