Hi @airzoink,

Is this a hosted instance @ ERPNext.com or your own instance?

And did you customize the code or upgrade from v7 to v8?

Thanks.

I’m running my own production instance. I upgraded from v7 to v8. i never checked this prior to upgrading v8 which i started around 8.0.14. Now, i’m in the latest 8.0.29.

I wonder whether this tool might help…jinja2.debugrenderer

still getting the same error in 8.0.33.

@EnSeal reports a similar error on save

One of our clients also has the same problem when opening the “Products” tab on his ERPNext.com hosted site. Maybe this is a problem with the new update?

Fixed in latest update!
