Cannot Save Delivery Note (v11): Argument 1 of Window.getComputedStyle is not an object

Dear colleagues,

strangely, when trying to save a Delivery Note on a v11 system, I receive in the browser console

TypeError: Argument 1 of Window.getComputedStyle is not an object.

and the document is not saved. The save function however works on other delivery notes in the same system. Has anyone observed this as well?

Not able to replicate this issue on v11

ERPNext: v11.1.53 (version-11)
Frappe Framework: v11.1.49 (version-11)

Maybe you can try to clear the browser cache and try.

Thanks for your feedback. Unfortunately, after reloading, the changes were lost and when I re-entered the data (as well as I remembered), it worked. I guess it must have been some content in the description field, but was so far unable to reproduce it. I guess some input combination / content leads to this, maybe someone else comes across this too…
