I’m very sorry for the inconvenience.
No problem. It would be very nice if we could get away from Postman in future - and you could help. 
I’m sorry, I’m not allowed to share the complete collection.
Is it not very convenient to remove some sensitive information and then share it? Let’s try to reproduce and locate it as much as possible.
The collection is relatively large. Going through everything would take too long - and I would certainly overlook a lot.
I could continue to try to import everything and report any errors, or create test data until everything works. Step by step…
The bigger problem is that the data currently ends up in a cloud, which is not what is wanted.
We are very sorry for any inconvenience caused to you. We already know the problem and will handle it.
