Cannot run samples with Video API Playground session & token

[rafaelnobrekz]

Hi! I'm trying out the SDK but am unable to run any of the samples.

1. I created an Application with "Video" enabled
2. I went into the Video API Playground, selected the account, app and relayed mode
3. Injected the generated values into the fields for some of the samples (Basic, CallKit, Video-Transformers)

Result from the Console:

Additionally, I also tried creating sessions and tokens through the server API using python and ruby:

from opentok import Client, MediaModes
import time

api_key = "<api_key>" // Found in Settings, Master
api_secret = "<api_secret>" // Found in Settings, below the api_key

client = Client(api_key, api_secret)

session = client.create_session(media_mode=MediaModes.relayed)

print("session_id:")
print(session.session_id)
print("token:")
print(session.generate_token(expire_time=int(time.time()) + 10000))

Output:

Traceback (most recent call last):

    raise AuthError("Failed to create session, invalid credentials")
opentok.exceptions.AuthError: Failed to create session, invalid credentials

During handling of the above exception, another exception occurred:

opentok.exceptions.RequestError: Failed to create session: Failed to create session, invalid credentials

Ruby attempt:

require "opentok"

api_key = "<api_key>"
api_secret = "<api_secret>"

opentok = OpenTok::OpenTok.new api_key, api_secret

session = opentok.create_session

session_id = session.session_id

puts "session_id:"
puts session_id

token = session.generate_token({
    :role        => :moderator,
    :expire_time => Time.now.to_i+(7 * 24 * 60 * 60) # one week
});

puts "token:"
puts token

What am I doing wrong? Thank you.

I've since realized with the hint from the Session inspector tool that the samples actually expect the ApplicationID when they mention API Key. That is very confusing! However, the backend session generation still doesn't work in any way I try it.

@rafaelnobrekz, likely your credentials were bad. They could've have been expired, for example.

Please try the following:

• From Video API Playground, create a session and publish video from your browser.
• From iOS Basic Video Chat, try to join that session and subscribe to the video that your browser is publishing.

The above should work.

@rafaelnobrekz I assume your issue was solved. If this is not the case please re-open the ticket
