TokenName is not hex-encoded: base16: input: invalid length

[volodyad]

Summary

This is duplicate of IntersectMBO/plutus#4236

I have added steps to reproduce
volodyad@589a263

On first transaction token mint and send to the script,
On second - token spent to and send back to the script, this transaction fails

Are there any ideas how to resolve or workaround this issue?

Steps to reproduce the behavior

Copy files from the commit or run form the commit itself

cabal build plutus-pab-local-cluster
cabal exec plutus-pab-local-cluster

run the contract
curl -H "Content-Type: application/json" -v -X POST -d '{"caID":{"tag":"MintTest"},"caWallet":{"getWalletId":"2d4cc31a4b3116ab86bfe529d30d9c362acd0b44"}}' localhost:9080/api/contract/activate
