3808896 - error: unknown command 'tasks' when running datasphere tasks via the Command Line

• Running the CLI to start a task chain shows: 
  • error: unknown command 'tasks'

    Make sure to always define the host using the --host option or by running datasphere config host set "<Server_URL>". Did you initialize the CLI by running datasphere config cache init --host "<Server_URL>"? Add option --help, -h or go to tinyurl.com/datasphere-cli-help for additional information.

• Executing commands such as:
  • datasphere tasks consent get
  • datasphere tasks chains run ...
  • datasphere tasks --help --host

1. Open a terminal where the Datasphere CLI is installed and authenticated.
2. Run: datasphere tasks consent get

A service discovery schema change delivered with Datasphere wave 2026.19 introduced a breaking change for older Datasphere CLI versions.
CLI versions prior to 2026.10.0 could not parse the updated discovery JSON (expecting a string where an array is now allowed), which prevents the CLI from registering the tasks command.

1. Update the CLI to the latest version (minimum 2026.10.0 required): npm install -g @sap/datasphere-cli
2. Verify the update: datasphere --version
3. Re-test the commands
4. If the issue persists, increase logging for troubleshooting, then re-run and collect the output:
   1. set LOG_LEVEL=6
   2. run the command that does not work
   3. collect the output
   4. set the log level back afterward: set LOG_LEVEL=1
   5. raise a support case to DS-API-CLI and attach the output in the case.
