Cannot read properties of undefined (reading 'toString') - Postman Collection

Posted on by MHarwoodUK

Hi all,

I can see a couple of threads on this but I can't find a solution in them.

We are trying to import the attached Postman collection as a Custom Connector via PowerApps > Data, but are getting the error Cannot read properties of undefined (reading 'toString'):

I assume there is something in the json file that isn't quite correct, but this file is from a supplier - I don't know what to look for, and it's hard to find somewhere there that will!

The file is here, as I can't upload json documents: https://eurowagens-my.sharepoint.com/:u:/p/m_harwood/EZb8obrYoPBJvRm9dd0grJMB-Ve2BPv4Xmq9GDZKUGFazA?e=75thPe

Can anyone advise how I can get this working please?

Thanks so much in advance,

Matt

I had the same issue. After some trial and error, though, I found out that the importer fails if the "code" attribute is missing from a response object or if it's value is null. It's missing for the "SetOrderGeneralInfo" response in the file you linked to, so adding it in should fix the issue and let you continue importing the file.
