DashboardPanelDistribution TypeError

[sara-vallejo]

Hello,

I want to use the DashboardPanelDistribution in my dashboard and i have tested the following. In my report I set:

report = Report(metrics=`ColumnDistributionMetrics(column_name="type"), timestamp=datetime.datetime.now(), tags=[])

Then the project is set as:

project = ws.create_project(MY_PROJECT_NAME)
project.dashboard.add_panel(
   DashboardPanelDistribution(
      title="Type distribution",
      filter=ReportFilter(metadata_values={}, tag_values=[]),
      value=PanelValue(
         field_path=ColumnDistribution.Metric.fields.current,
         metric_id="ColumnDistributionMetric",
         metric_args={"column_name.name": "type"}
      ),
      barmode=HistBarMode.STACK
)

then I add the reports as:

ws.add_report(report)

However, I get the following error when running evidently ui:
TypeError: Subscripted generics cannot be used with class and instance checks

My setup is:

• Python 3.9.2
• evidently==0.4.38
