RPCError: Invalid parameters

[ak4728]

I sometimes receive the following error when I try to get replies of the account.

During handling of the above exception, another exception occurred:

UnhandledRPCError: Invalid parameters

It throws this error sometimes though. In other times, it works without a problem. Is this because of something on my end?

This is caused by the set RPC node
