Undefined property: CI::$mdl_invoice_amounts on recurring invoices

Good day everyone,

Firstly, great product! Definitely the best out there.

Everything works fine, except for my recurring invoices. I tried using recurring invoices in 1.5.4, but then I saw that there was a bug on not retrieving the taxes correctly, which resulted in an error and said it was scheduled to be fixed in 1.5.5. I have upgraded my version to 1.5.5, but I’m receiving a different error this time:

Undefined property: CI::$mdl_invoice_amounts

It generates a new invoice, but the amount is left 0. Could someone please assist with what I’m doing wrong. I am clicking on Save first before creating the recurring invoice.

Here is the full trace:

I 2nd this - as of 1.5.5, recurring invoices are now being generated however, there are no items listed in the invoice.

I’m still running 1.5.4, but my error is a different variable.

Sadly this is the second time that I’ve applied an update to InvoicePlane and found recurring invoices to be broken the following month.

I wish this were more thoroughly tested as it’s making me begin to question whether or not to update, which isn’t something I should be asking about my billing software…

Is it possible to roll back to a previous version?

This error was fixed in version 1.5.5.

If I had the time or money to pay someone to do this, I would definitly test more. But I don’t have neither. So it is a task of the community to help test the software and fix bugs. :slight_smile:

This is because the model has not been loaded before
Add to file /application/modules/invoices/controllers/Cron.php on line 31


and all will run smoothly

That prevented the CRON errors but now all recurring invoices are empty.

In file /application/modules/invoices/controllers/Cron.php
on line 61
$this->mdl_invoices->copy_invoice($source_id, $target_id, true);

set this to false
$this->mdl_invoices->copy_invoice($source_id, $target_id, false);

on my case it’s work, recurring invoice not empty

Thanks to @smile for his fix. Just test it and it works I just made a Pull Request it should be fix in the next version :slight_smile:
