mintDIP721 - (variant {Err = variant { Unauthorized }}) and The Replica returned an error: code 5, message: "canister xxxx-xxx-xxx-xxxx-xxxx trapped: unreachable

[sakunix]

Used command:
dfx canister call nft mintDip721 "(principal "7fi54-4ehlq-on5si-izkkp-n3ism-wipnz-chyha-m7adi-sqjty-rwndi-xae", vec {record { purpose = variant { Preview}; key_val_data= vec { record {key="NFT 1"; val= variant {TextContent="png"}}}; data= blob"100, 97, 116,..., 103, 103, 103, 61, 61"}})"

I tried the "approval-permissions" version :
https://github.com/Psychedelic/DIP721/tree/refactor/approval-permissions

error: "The Replica returned an error: code 5, message: "canister xxxx-xxx-xxx-xxxx-xxxx trapped: unreachable""
