Description of expected behavior and the observed behavior
Creating a pn.widgets.Tabulator where a column
- Is of datetime type
- contains at least one but not all pd.NaT
raises the following error, not allowing to display the app:
ValueError: Out of range float values are not JSON compliant
ERROR:bokeh.server.views.ws:Bokeh Server internal error: server failed to handle a message, closing connection
If we edit a datetime from a full pd.NaT column (ending in the same situation as if we initialised from a non full of pd.NaT column), it works.
