I had a similar issue when sending attachments.
I needed to change attachments[:report]
toattachments['report']
old:
def email_report(email, report)
attachments[:report] = File.read(report)
mail(to: email, subject: 'report')
end
new
def email_report(email, report)
attachments['report'] = File.read(report)
mail(to: email, subject: 'report')
end
I suspect something similar is happening to you.
