OP CLI - Unable to build a list of item categories

Hi cronekorkn and @raggy! Thanks for bringing this up. At the first glance, this seems as a rate limit issue coming specifically from op item create, as you were also guessing. However, I have a few questions in order to be 100% sure that we are correct, and if we are, to help us design a solution for this:
0. How many op item create operations do you do in total? (do not count the other operations)
1. What is the exact command you are doing for creating all these items? Do you create them using a for loop to repeat a op item create operation or do you use piped input to tell the creation command what items to create (i.e. op item list | op item create -, for example)?

All the best,
Andi
