E-Mail that's not multipart produces `NoMethodError` about helpy_imap HOT 1 CLOSED

As I ran into the same issue I tried to dig a bit deeper, and the conditions.rb file doesn't seem to be the culprit. For testing purposes and to rule it out, I commented out the line containing @matcher.match(message.body.decoded), but the error still ocurred after that.

Still looking for a solution I looked for occurrences of the keyword "multipart" and stumbled across the following lines of code in the imap_processor.rb in the helpy_imap folder:
def get_content_from_mail if mail_is_mail @email.multipart? ? (@email.text_part ? @email.text_part.body.decoded : nil) : @email.body.decoded else MailExtract.new(@email.body).body end end

Curious as I am, I wanted to know if the email.body could be nil, although by looking at the code this should never be the case. After testing, I was sure that this is not the case.

As of now, I haven't found a solution, but I'll try to figure it out and I will keep the community updated.

Best regards,
Phil

EDIT: I figured it out! The problem lies in the imap_processor.rb, because a plain-text mail doesn't seem to have a text_part.body, just a .body. The following lines of code will fix this problem:

def raw_body_from_mail if @email.multipart? mail_is_mail ? @email.text_part.body.decoded : @email.raw_body else mail_is_mail ? @email.body.decoded : @email.raw_body end end
