Setup:
setting up midas, starting mhttpd and mlogger and running fetest.

The History page and the javascript mjsonrpc client are both able to fetch historical data for test_slow/data. Javascript code used is included here:

mjsonrpc_call(
  "hs_read_arraybuffer",
  {
    start_time: Math.floor((new Date()).getTime() /1000) - 1000,
    end_time: Math.floor((new Date()).getTime() /1000),
    events: ["test_slow/data"],
    tags: ["data"],
    index: [0],
  },
  "arraybuffer"
).then(console.log)

However, the python client does not find any valid events:

Setup:
An exptab is created and the environment variables MIDAS_EXPTAB and MIDAS_EXPT_NAME and MIDASSYS are set (together with the correct PATH)

Running /midas/python/examples/basic_hist_script.py and typing in data:

Valid events are:
* Run transitions
* rrandom/SLOW
* test_slow/data
Enter event name: test_slow/data
Valid tags for test_slow/data are:
* data
Enter tag name: data
Event/tag test_slow/data/data has 1 elements
How many hours: 1
Interval in seconds: 1 # other values were also tested, without success
0 entries found

We expect entries to be found, however do not.

Tested setups:
Macbook Pro Sequoia 15.3 with Python 3.13.2, ROOT latest, midas bitbucket commit 84c7ef7
Windows 11 with Python 3.11, ROOT latest, midas latest commit (development branch)
