User API: API fails if we skip component field, which is not marked as required

[NihalJain]

Steps to reproduce:

curl -X 'GET' \
  'http://localhost:9000/users/{username}' \
  -H 'accept: application/json' \
  -H 'Authorization: Basic dGVzdDp0ZXN0'

Expected:
Either

• Details of user is returned, irrespective of component type
• OR, the field should be marked as required in SwaggerUI

Actual:

{
  "code": 400,
  "error": "Cannot invoke \"org.apache.pinot.spi.config.user.ComponentType.name()\" because \"componentType\" is null"
}

Need to audit all User APIs and fix them appropriately.

I plan to provide a fix on this, once the expected behaviour is confirmed by the team!

Good catch! The easier fix is to mark component type as required
