Hi!

 

I'm trying to create a Zap between Notion and WAVE Invoicing. I’ve tried multiple times, I think I’m getting closer, but now I’m getting the error “

Failed to create an invoice in Wave

Cannot convert undefined or null to object”

 

Anyone know why and what this is?

Hey there @Eg9876!  

Thanks for reaching out about this. It’s likely that there’s a value that’s been selected for one of the fields on that Create Invoice action that’s not quite what Wave is expecting to receive. It’s a bit hard to know from that error exactly which field it is but usually dropdown fields where a custom value have been supplied are a good first place to start. 

For example, dropdown fields like the Customer and Product fields can sometimes have a customer or product name supplied instead of an ID number. In which case it may be worth clicking the Or add search step button next to the field to add a search action to help locate the relevant IDs:

If that’s not the case here can you send a screenshot showing what’s been selected for each field on the Create Invoice action? That’ll help us to get a better idea of what else might be causing the error. Don’t forget to remove/hide any private information like names, email addresses etc from any screenshots first.

Looking forward to hearing from you! 🙂

Can you please share a screenshot on how did you configure the Wave action?
