ThreadSo, if one of those maps is empty, it means the asset didn't have them
5 messages · –A C A Hmm... So, I guess my issue only occurred because I'm testing on testnet? Here's my check step: 1. test collection: testworkshop 2. contract hosted at splltutorial 3. created an asset through AH interface: 1099566958569 4. checked the asset in atomicassets's assets table: https://testnet.waxblock.io/account/atomicassets?code=atomicassets&scope=waxchainuser&table=assets&lower_bound=1099566958569&upper_bound=1099566958569&limit=10#contract-tables << here we can see that immutable and mutable are empty.
