}`

When i execute my code in remix-IDE, this function give me error 0x815e1d64 => invalidSigner.
Why ?

Edit: FIXED

Did you managed to find a fix for this issue?
I am using hardhat and the transactions fails with the same error. However, if when I encode the same parameters and function selector and send transaction using Metamask, the transaction will not fail.

[jecombe]

Sorry for time.. did you fix that ? I've fixed and i can explain

[wilson-ang]

Yes, I managed to fix it. For me the issue was because I didn't specify the forked chain id.

Hey! Can you tell what the issue was? Was it the chainId for you, too? Thanks!
