Can you format your code when you paste it? It makes it much easier to read!
I copied a bit of yours to https://beautifier.io/ to test
{
“msg”: “method”,
“method”: “sendMessage”,
“params”: [{
"_id": “user-id”,
“rid”: “room-id,”, <<< extra comma here after room-id?
“msg”: “Hello Hassan!”
}],
“id”: “48”
}
It should look like this from the docs?
{
"msg": "method",
"method": "sendMessage",
"id": "42",
"params": [
{
"_id": "message-id",
"rid": "room-id",
"msg": "Hello World!"
}
]
}
Yours seems to be missing:
"_id": "message-id",
Please go back and check all your code carefully, and use our examples to test.
