This article list down the configurations that you need to do first, before you can view your TM1 Web sheets and/or Cube Views within Canvas:

Search and update for CrossDomainAccessList and set the value to ‘*’ or to the appropriate domain. For further details, please check IBM’s documentation on this.

Search and update for LegacyUrlApiSessionDiscoveryEnabled and set the value to ‘False’ as Canvas is using URL API to render your Websheets and Cubeviews. 

In Services, restart IBM Cognos TM1 Application Server.

Verify that you are able to login into your instance via tm1web. Use the TM1 web url http://<servername>:9510/tm1web/ and test the connection.

Go into your <canvas>/WEB-INF directory and open up instances.json file. Check that the tm1webUri property in there matches the server name and the port where you access your TM1 Web (this is typically http://localhost:9510/tm1web).

• dispatcherURI
• tm1WebLoginAtServer
