Closes: #5
Here we provide a workaround for servers that don't follow the JSON-RPC 2.0 specification for error objects.
According to the specification, an error should be an object containing
code
,message
, anddata
properties (see: https://www.jsonrpc.org/specification#error_object).Unfortunately, Electrs returns an error as a string (see: Blockstream/esplora#453).
We define an error unmarshaling function to handle both types of errors.
Sample outputs from servers that the client has to handle:
ElectrumX
