Insights is connected to the DB but it not loading the UI

[kitunzit]

Good day.
Insight app has connected to the MariaDB, on the second step/window showing " Help Us improve" i press skip & two messages are displayed " internal server error" & "Syncing Data source. This may take a while. Please wait....". See attached image.
Am running ERPNext 15 hosted on cloud clusters.
Any help will be appreciated.
Thanks

Please share the traceback from the browser console. To do that open the browser console after you get "Internal Sever Error" and send the last error message

I was also getting same error with postgresdb. Attached screenshot of the error message from the logs. I modified the code in the file insights_data_source_v3.py line 62 as below to make it work.

self.db_set("is_frappe_db", 0)

Next it was failing in the file ibis_utils.py line 388. I replaced with below code to make it work.

res = res.replace({pd.NaT: None, np.nan: None})
