Cannot unsubscribe

[0xvoidmain]

Sub message
{"action":"subscribe","subscriptions":[{"topic":"crypto_prices_chainlink","type":"*","filters":"{"symbol":"BTC/USD"}"}]}

Unsub message
{"action":"unsubscribe","subscriptions":[{"topic":"crypto_prices_chainlink","type":"*","filters":"{"symbol":"BTC/USD"}"}]}

And then I receive error like this:
{"message": "Invalid request body", "connectionId":"UOqz2cMTrPECIdg=", "requestId":"UOrN7FVTrPEEO5g="}

Just remove the optional fields (filters, clob_auth, ..,).
