Rest API get nodes failure (v25)

[romanrap]

HI

i have the following issue, when calling this rest api endpoint:

urllib3.connectionpool http://slurm:6820 "GET /slurm/v0.0.43/nodes/?update_time=1762768086 HTTP/1.1" 500 719

i get this error:

  "errors": [
    {
      "description": "Unable to query partitions",
      "error_number": -1,
      "error": "Unspecified error",
      "source": "_dump_nodes"
    }
  ],
  "warnings": [

    },

    "slurm": {
      "version": {

        "micro": "4",
        "minor": "05"
      },
      "release": "25.05.4",
      "cluster": "mycluster"
    }
  }
}

it seems the issue is the update time

first call is without update time, it works, then i store the update time and send it again and all subsequent fails

i use the same logic with get_jobs and no issues, please advice.

I am unable to reproduce, I am a getting HTTP/1.1 304 NOT MODIFIED with wget --header="X-SLURM-USER-TOKEN:${SLURM_JWT}" -q -S -O - 'http://localhost:6820/slurm/v0.0.43/nodes?update_time=1763038492' .

Can you try rest calls on another slurm instance?
Can you come up with a minimal, but complete, set of steps that is reproduces the bug.
