OpenSSL.SSLStream does not support byte I/O

[femtotrader]

Hello,

The following code

# Import the WebSockets library for WebSocket communication and JSON for data handling
using WebSockets
using JSON

# Function to fetch data from Binance WebSocket API
function fetch_binance_data(url::String)
    # Open a WebSocket connection to the provided URL
    WebSockets.open(url) do ws
        # Loop to continuously read incoming messages from WebSocket
        while true
            try
                # Read a single message from the WebSocket connection
                msg = read(ws, String)
                
                # Parse the JSON message into a Julia dictionary
                data = JSON.parse(msg)
                
                # Print the received data (you may replace this with other processing code)
                println(data)
            catch e
                # Print any errors encountered while reading/parsing data
                println("Error encountered: $e")
                
                # Break out of the loop on error to avoid infinite error printing
                break
            end
        end
    end
end

# Binance WebSocket URL to fetch depth data for ADA/USDT and BTC/USDT pairs
url = "wss://stream.binance.com:9443/stream?streams=adausdt@depth20@100ms/btcusdt@depth20@100ms"

# Call the function to initiate WebSocket data fetching
fetch_binance_data(url)

raises

Error encountered: ErrorException("OpenSSL.SSLStream does not support byte I/O")

I have no idea why?

Best regards

PS :

# Import the HTTP library for WebSocket communication and JSON for data handling
using HTTP
using JSON

# Function to fetch data from Binance WebSocket API
function fetch_binance_data(url::String)
    # Open a WebSocket connection to the provided URL
    HTTP.WebSockets.open(url) do ws
        # Loop to continuously read incoming messages from WebSocket
        for msg in ws
            # Parse the JSON message into a Julia dictionary
            data = JSON.parse(msg)
            
            # Print the received data (you may replace this with other processing code)
            println(data)
        end
    end
end

# Binance WebSocket URL to fetch depth data for ADA/USDT and BTC/USDT pairs
url = "wss://stream.binance.com:9443/stream?streams=adausdt@depth20@100ms/btcusdt@depth20@100ms"

# Call the function to initiate WebSocket data fetching
fetch_binance_data(url)

is a workaround
