2 years ago Hi,
I started having the same error.
First I had a problem with the Ganache chain, that I fixed changing it to "1337" and not the one I was seeing as Network Id, since are not the same. (https://stackoverflow.com/questions/70731492/the-transaction-declared-chain-id-5777-but-the-connected-node-is-on-1337)
I kept having an error, the one you are having, so I changed in Ganache the port to 127.0.0.1:8545. (and in the code)
After that, a new error appeared, related with the gasPrice. Error:

What I found: https://stackoverflow.com/questions/72594258/userwarning-there-was-an-issue-with-the-method-eth-maxpriorityfeepergas-calcul
Just adding the "gasPrice" variable was fixed.
I hope it is helpful.
