LayerSwitcher: Using attribute table seems to crash Hajk whenever the layer contains a date/dateTime field using QGIS Server

Describe the bug When activating the setting to enable the attribute table, the Hajk client crashes (becomes completely white) when clicking on the attribute table button if the layer contains a dateTime/date field, for instance Date in Oracle or timestamp in PostgreSQL.

The dateTime/date field seems to look something like this in the response from QGIS Server:

(GetFeature)

"DATUM": "2022-04-28T00:00:00.000"

(DescribeFeatureType)

  {
                    "alias": "Dating",
                    "localType": "date",
                    "name": "DATUM",
                    "nillable": "true",
                    "type": "date"
  }

I have tried altering the settings below for the layer in QGIS, but to no effect on the attribute table working or not. MUI seems to only accept Date() objects after all. Perhaps valueGetter can be used to convert the dateTime/date strings somehow? Link to MUI docs

To Reproduce Activate the functionality in Admin for a layer containing any number of dateTime fields. Click on the attribute table icon.

The following type of error will display:

ERROR MUI:datecolumn type only acceptsDateobjects as values. UsevalueGetterto transform the value into aDateobject. Row ID: 0, field: "DATUM".

Expected behavior The attribute table shows up as expected.

Additional context Tested using Oracle and PostgreSQL. Using QGIS/QGIS Server 3.34. I have not tested it with for instance Geoserver. Hajk version 3.14 RC1.
