Proven always returns `unsuccessful response 422`

[imduchuyyy]

Hi Taiko team,
I have run the Taiko proposal node from this script https://github.com/taikoxyz/simple-taiko-node. And I try to connect to all of the proven listed on Proven Market.

All the node return unsuccessful response 422.

Logs:

Hi,
I was experiencing the same issue, and it was resolved as follows:
You can add all the provers in the prover market (https://taiko.xyz/docs/reference/prover-market-page) separated by commas. Then, you can increase the BLOCK_PROPOSAL_FEE parameter. For example: 50
