  • Its complicated to know where is the issue since you're actually doing more than 1 transaction in your test; I suggest that you make no more than 1 transaction per test.. that way you can narrow down your issue

  • if you can add more code it would be helpful to find out the issue (a feeling says the deployer is undefined here) Commented Jan 21, 2023 at 15:53
