calling functions directly on deployed smart contract works perfectly fine: enter image description here

Did you send value when deploying the contract? Here is a picture of where you need to include the value when deploying:

  • yes, calling contract directly works perfectly fine (as I described in the main post) only when running unit tests - some tests are failing (some, not all)
