invalid transaction type

remove the quotes

sorry - ignore the quote

you're sure that's the part that's throwing the error? based on the line # and stack trace? cos... I don't think record.Type VENDOR_BILL is a bad type 🙂

Same issue

you have the record module included in your define, right? think that would give a different error sooner in the process though in your script? and any library modules?

I would print the

recordType

param inside the function and see what is being received.

It prints the expected type - I pasted the full script in the main channel.

Maybe a dumb suggestion but did you verify your record module is in fact pointing to the record module? I made that mistake a bit ago where I had record and another module flipped around in the order of instantiation and it was causing me headaches

Thanks for the suggestion, I rewrote the whole thing in the end as it wasn’t well designed.
