Thanks for responding!

Yes that’s the complete error message.

So, this isn’t actually an error about a character entity – those character entities are the result of a Ruby error being double-escaped in HTML.

The error actually being emitted is:

"#<NoMethodError: undefined method `instances' for #<#<Class:0x3471635c>:0x2346a459>\nDid you mean?  instance_of?>"

Where that’s coming from, I’m not sure, unfortunately – is that the full error message?

When I try to run the background job of Import Data, EAD I get the following error:


Error: #<NoMethodError: undefined method `instances' for #<#<Class:0x3471635c>:0x2346a459>
Did you mean?  instance_of?>

I have replaced any stylized characters and looked for rogue symbols and empty tags. I tried reformatting the dates to YYYY-MM-DD.
I’ve also run it through Harvard Archivesspace_checker and it passes.

Attached is the ead file.

If anyone can let me know what the error message means that would be fantastic.
