Currently running Civi 5.49.1 but I've been seeing this behaviour for a little while now. I've got Civi set up to apply VAT (sales tax) and issue invoices, which go out with event registration confirmation emails. All good.

What used to happen as far as I can recall is that if the event was free, then no invoice was created or sent. Ideal.

However what I'm seeing is that participants are being sent confirmation emails with an attached file called 'invoice.pdf' which is blank. Not good.

Before I log this as an issue in Gitlab, is there a recent change in the settings/config around invoicing that I'm missing, or is this a bug that others are seeing?

Noticed a similar thing when registering users via the back end, non paid event and sending a confirmation email with tax enabled. Blank invoice.pdf attached to the email. Have you logged a bug report by any chance or resolved the issue?

  • just putting a note for myself that we also had a report of this but have not solved yet but the example we were told about was not a free event (but we didn't get all the evidence sent on to us). r26419
