Start with the reported stack trace at web3_request_manager.js:124 and reproduce the transaction against BSC testnet, chain ID 97. Compare the request and returned response with the working Ethereum testnet case; done means identifying whether the failure is in the extension or the RPC service and documenting or fixing it with a reproducible test.
