I have followed this article to use ITX.
I enabled ITX and added API request of relay transaction.
However, I got an error that says ITX is only for bate user, when I called relay_getBalance
method.
(node:13447) UnhandledPromiseRejectionWarning: Error: processing response error (body="{\"jsonrpc\":\"2.0\",\"id\":42,\"error\":{\"code\":-32004,\"message\":\"This method is currently only available for registered ITX beta users\"}}", error={"code":-32004}, requestBody="{\"method\":\"relay_getBalance\",\"params\":[\"0x027xxxD6D\"],\"id\":42,\"jsonrpc\":\"2.0\"}", requestMethod="POST", url="https://polygon-mainnet.infura.io/v3/848xxxxx13", code=SERVER_ERROR, version=web/5.5.1)
Could you please teach me how to enable or register beta user?
