TaskResponse error field additionalProperties is the wrong type

Version
Pulpcore 3.29.2
RPM 3.22.2
Certguard 1.6.5

Installed with podman compose

Describe the bug
The error field in TaskResponse is defined as the type "object" with the "additionalProperties" type object. However, it looks like the returned value is actually the type "object" with the properties of the objects being strings.

"error": {
    "traceback": "  File \"/...",
    "description": "Cannot connect..."
  },

Traceback and Description are values of type string.

My understanding of this comes from this documentation here, which says additionalProperties specifies the types of the values.
To Reproduce
Sync a repository with a bad URL and observe the error in the TaskResponse. There are two fields, traceback and description, with values of type string. However, if you query the docs it says the type is object.

Expected behavior
I would expect the api.json to define the additionalProperties as type string instead of type object

Additional context
This is causing some issues in our generated library here that we've worked around manually here: https://github.com/content-services/zest/commit/ee55f31f4234ca312ca13fc860b8cd0ca923b2cb

Start by locating the TaskResponse schema and the api.json/OpenAPI definition exposed by the documentation. Reproduce the response by syncing a repository with a bad URL, then verify that the documented error mapping treats traceback and description values as strings.
