I’m getting this error “Wrong type NilClass. Not allowed!” in my integration with mailchimp, using field mapping.
Hi there Felix,
This is a known issue that I’m hoping to fix soon!
Here’s the actual description I’ve got in our issue tracker:
“Having “e-mail” in the form results in this error. This is because the fuzzy-extract for “email” doesn’t match on it.”
Are you explicitly mapping your email field to the EMAIL merge var in MailChimp?
I have the same problem and the solution of Aaron works for me.
BUT: In German “email” is written correctly “E-Mail”. Everything else is wrong.
I try to deliver professional services and I try to write correctly. That’s why it’s not a very big issue for me but a splash on my site.
