​
NOTE: -32000 is used for many server errors. Here are a few common examples:
"already known"
This generally means the transaction already posted and is on the node in a pending state. Sometimes this error occurs when transactions fail at first but are retried when the node already knows of them
"Unspecified origin not on whitelist"
This error means whoever is making the request is not on the whitelist for using your API key.
"filter not found"
Filters expire after 5 minutes of inactivity so if it's not found the filter likely expired.
"Request timed out. Client should retry."
Gateway timeouts (usually from nodes). Clients should retry the request.
"transaction underpriced"
Transaction was sent with too low gas. Re-send the transaction with higher gas!
