Trying to copy an valid assembly build to a new one and saving it, but getting an

UNEXPECTED_ERROR

any thoughts?

try in different browser and see if you get a "better" error

Does that really matter with a user event script?

yeah internet explorer used to reguarly give me more explicit error than unexpected chrome would give

No luck, same unexpected_error

I would check the scripted records on assembly build and turn them off one by one to see if the error goes away

using record.create does function instead of the record.copy

sounds frustrating

Sure is but since record.create does work, I'll use that instead.
