Problem
When connected to Exasol using a secure WebSocket connection (wss://), requests with a long text length (>2KB) may cause errors.
For example, the error may be similar to the following error.
Unsupported WebSocket opcode
Workaround
Disabling encryption will fix the problem (i.e. using 'ws://' instead of 'wss://').
Please be aware that the connection will then be insecure.
