      I want to random generate throughputProbingMinConcurrency and throughputProbingMaxConcurrency at runtime, but the current test framework had issue dealing with it at runtime set. The issue is throughputProbingInitialConcurrency is considered string instead of integer in the min/max checks

      "throughputProbingInitialConcurrency": {"min": 8, "max": 256, "fuzz_at": ["startup"]},
        "throughputProbingMinConcurrency": {
            "min": 4,
            "max": "throughputProbingInitialConcurrency",
            "fuzz_at": ["startup"],
        },
        "throughputProbingMaxConcurrency": {
            "min": "throughputProbingInitialConcurrency",
            "max": 128,
            "fuzz_at": ["startup"],
        },

      Error:

      TypeError: can only concatenate str (not "int") to str
