Contract Signing on Unichain is broken

[simoncoop1]

signing any contract on Unichain gives an error

"Transaction parameter 'gasPrice' is not a valid hex string"

/tmp/.mount_Frame-nxy5FX/resources/app.asar/node_modules/@ethereumjs/tx/node_modules/@ethereumjs/util/dist/bytes.js:147
            throw new Error(`Cannot convert string to buffer. toBuffer only supports 0x-prefixed hex strings and this string was given: ${v}`);

Then if I repeat the above Frame crashes with uncaught Exception

"Transaction parameter 'gasPrice' is not a valid hex string",

Uncaught Exception! Error [ERR_IPC_CHANNEL_CLOSED]: Channel closed
    at new NodeError (node:internal/errors:393:5)

I have tested on one other wallet and issue is only on Frame
