Issue summary

When one pulls Orders data from API with auto-iteraton (no_iter_next=True), library iterates over pages and when it hits page 476 an error is thrown. Also, looks like there are memory problems because of this recursion as our servers just die and we have to reboot them, although I have no clear evidence of this. It’s unknown if this impacts other data type (Customers, Products…) - although it’s very likely it does as the code that crashes is generic collections code.

edited: Seems like default recursion limit in py3 is 1000. The code does 2 * 475 = 950 iterations. Looks like 50 is for other operations the code is doing. The code crashes at the same place, always.

Expected behavior

No error is thrown, code continues.

Actual behavior

Error is thrown:

Steps to reproduce the problem

1. Make sure you have enough test data in shop - you can set page size to a fairly small number (e.g. 50) to have to use less data
2. Call API with python library with auto-iteration ON
3. Error raises
