Cannot open Dtale with browser from Notebook

[GiacomoTel]

Hi using this code in a jupyter notebook

import dtale
import dtale.app as dtale_app
import dtale.global_state as global_state

global_state.set_app_settings(dict(enable_custom_filters=True))
dtale_app.USE_NGROK = True
dtale.show(dfUnion,host='localhost',enable_custom_filters=True)

it doesn't open the instance in the browser but instead it gives me this error

---

IndexError Traceback (most recent call last)
Cell In[6], line 7
5 global_state.set_app_settings(dict(enable_custom_filters=True))
6 dtale_app.USE_NGROK = True
----> 7 dtale.show(dfUnion,enable_custom_filters=True)

tunnel_url = tunnel_url.replace("https", "http")

ecc ....
return tunnel_url
IndexError: list index out of range

Can anyone show me how to open the browser view from visual studio jupyter notebook ?
Thank you

I'd try using jupyter-server-proxy

Thank you , it helped , we are making progress but now it open a page on the browser
whit this url
/user/GiacomoTel/proxy/40000/dtale/main/1/40000/dtale/main/1
which is not reachable

Try taking /40000/dtale/main/1 off the end, looks like it's repeated. Just wanna see if that endpoint works. If ti does I'll look into why its repeating
