Getting a 409 error calling op-connect from Terraform

Update - this is caused by 2 API update requests being done in parallel on the same vault.  If terraform completes one before starting the next then it works. Adding :

--parallelism=1

 lets things work, but it really impacts performance if you have a lot of other resources.  We need some way to say that 1password resources must be applied single-threaded but its fine for other resource types to be applied in parallel.

There is the same problem in ansible, and you need to use these to prevent multiple concurrent updates of 1password:

serial: 1   # this stops multiple hosts being updated at once
forks: 1    # this stops multiple concurrent updates on the same host, may not be necessary

to ensure you dont get 2 happening at once.

Why is this?  It seems to be a failing of the API.
