UserError: TypeError on line 1: expected delayed value, got 'fn'

[gavinharris-dev]

The below scenario is doing the following:

1. List an Asset at a Contract address
2. Using the Smart Contract, allow a user to spend the UTxO

The contract is not generated by Helios and seems to be using functionality that is as yet not supported.

[nielstron]

Is the contract by any chance written in PlutusTx? j am facing the same error

[christianschmitz]

I believe v0.13.1 fixes this. chooseList was missing a delay/force

[gavinharris-dev]

Going to be looking into this again quite soon so will provide an update based on Helios 14+

[gavinharris-dev]

This is now fixed and verified against the contract I was testing with. Thank you!!
