Websocket: Ignore Self Signed Certificates (How?)

[CudaNet]

Using Lua 5.1.5 (I know, old) and trying to get past an error:
starttls: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed:self signed certificate

I've read through the websocket section and I'm not entirely sure how to bypass this l like I would using wscat (wscat --no-check -c):
`
local uri = "wss://"..<$IP_ADDRESS>.."<$ENDPOINT>=".. <$VARIABLE>
local headers = {["Cookie"] = "TOKEN=" .. sessionCookie }

local ws = assert(websocket.new_from_uri(uri, headers))
assert(ws:connect())
`

Any suggestions/assistance is greatly appreciated. I'm using this module successfully for other projects, however their certs are not self-signed.

local openssl_ctx = require "openssl.ssl.context"
local http_tls = require "http.tls"

-- Set up a TLS context that doesn't do verification
local tls_ctx = http_tls.new_client_context()
tls_ctx:setVerify(openssl_ctx.VERIFY_NONE)

local ws = assert(websocket.new_from_uri(uri, headers))
ws.request.ctx = tls_ctx
assert(ws:connect())
