   Hi @ycloud-sean , this error means that your server doesn't implement the method - could you share more details on whether your server actually implements this or not?

   If the server is written in Typescript and uses a late-model version of the Typescript SDK, this would be handled automatically, with no need for the developer to write boilerplate code for handling the logging/setLevel request or for filtering messages according to the client's requested level.

   These two PRs added the feature to the TS SDK:

   • Automatic handling of logging level  typescript-sdk#882
   • Fix automatic log level handling for sessionless connections typescript-sdk#917

   We need to get other SDK maintainers to implement this feature as well. Assuming your server is not written in Typescript, please raise an issue with the SDK project you are building upon and reference this comment.
