📄 Description

The Google Cloud Storage API does not allow it either (see documentation). Trying to compose more than 32 objects at once qualifies as a 400 BadRequest. This is the body that GCS returns in such a case:

{
  "error": {
    "code": 400,
    "message": "The number of source components provided (33) exceeds the maximum (32)",
    "errors": [
      {
        "message": "The number of source components provided (33) exceeds the maximum (32)",
        "domain": "global",
        "reason": "invalid"
      }
    ]
  }
}

Note that GCS supports composing more than 32 objects into one. But it requires multiple compose calls, each one composing at most 32 objects in one go.
