I am trying to get the test code of the pinata-party working (https://medium.com/pinata/how-to-create-nfts-like-nba-top-shot-with-flow-and-ipfs-701296944bf).
It works fine to the point that I try and send a transaction:
flow transactions send --code "./transactions/MintPinataParty.cdc" --signer emulator-account
When I send that I get the error:
❌ Transaction Error execution error code 1006: [Error Code: 1006] invalid proposal key: public key 0 on account f8d6e0586b0a20c7 does not have a valid signature: [Error Code: 1009] invalid envelope key: public key 0 on account f8d6e0586b0a20c7 does not have a valid signature: signature is not valid
Anyone have any idea where this is coming from?
Thanks.
For me, the issue was that the private key in my flow.json file did not match the private key being used when starting the emulator. I was running the emulator via the Run Emulator command in VS Code. The private key being used for the emulator was in the command output.
