[inquiry]testing error

[puffanddmx]

[q1] I was creating my own runtime and testing unit transfer to alice -> bob using kitchen node recipes. However, the transmission for extrinsic was not successful and the following error message was obtained. I didn't even put it in the instant seal block. The tx interpretation seems to be different, maybe. how can i solve this?

-error log Failed to submit extrinsic: Extrinsic verification error: Execution(ApiError("Could not convert parameter tx between node and runtime: No such variant in enum MultiSignature"))

[q2] when i build my custom runtime(cargo build --release -p my _runtime), i got this error . how can i solve this?

[q1] I think it may be possible that you are encountering one of these two issues: 1) https://polkadot.js.org/api/start/FAQ.html#the-node-returns-a-could-not-convert-error-on-send, 2) https://polkadot.js.org/api/start/FAQ.html#i-cannot-send-transactions-from-my-node-template-based-chain. [q2] I think I need to see more of your code to help with this.
