Feedback for “Hello, World! - with Mesh”

Hi,

I am testing out Aiken. The last part where I need to unlock the funds in the contract. I follow the instructions, with blockfrost account setup and till lock the contract. It is working fine. The last part where I run the command to unlock the funds, I encountered the following errors:

% node hello-world-unlock.mjs e909e25eb77310ed9b43cf3ba297e96b4fdacbf6190c40bad7b7824f2bc7933a

throw Error(

I am not sure how to rectify "Transaction information is incomplete while no fetcher instance is provided".

Please advise.

Thanks,

Andy
