I'm following along the docs in order to call eth_estimateGas with Relay's JSON RPC endpoint:
https://eth.wiki/json-rpc/API#parameters-25
Here's my code:
const params = JSON.stringify({
to: '0xD79FFD274Bc1c0c9695fda8f774bf6E7B9225EAF',
data: '0x4641257d',
})
const result = await relayer.call('eth_estimateGas', [params, 'latest'])
But, I'm getting this error:
{
jsonrpc: '2.0',
id: 1,
error: {
code: -32602,
message: 'invalid argument 0: json: cannot unmarshal string into Go value of type ethapi.CallArgs'
}
}
Anyone know what the error means?

Hi @jg22 ,
Can you try without stringifying your params
const params = {
to: '0xD79FFD274Bc1c0c9695fda8f774bf6E7B9225EAF',
data: '0x4641257d',
}
const result = await relayer.call('eth_estimateGas', [params, 'latest'])

I'm not able to. The function signature for call is call(method: string, params: string[]): Promise<JsonRpcResponse>;
. I'm on node ts btw.
Regardless, I did try to force the object as a param like you suggested by transpiling without type checking, but that didn't work either (forgot what the error was).
@dylkil any updates on this issue? I'm running into the same problem when trying to call eth_estimateGas
via a relayer
