Environment

Tanzu Application Platform

Resolution

The error is caused by an incorrect YAML structure in the configuration file. Refer: Scale workloads.

Incorrect Configuration:

yaml:

cartographer:
  concurrency:
    max_workloads: 10
    max_deliveries: 10
    max_runnables: 10

Correct Configuration:

yaml:

cartographer:
  cartographer:
    concurrency:
      max_workloads: 10
      max_deliveries: 10
      max_runnables: 10
