unable to save webmap from notebook

SB9 — Sat, 01 May 2021 16:56:21 GMT

I am learning Python through ArcGIS Notebooks. In the lesson:

https://www.arcgis.com/home/item.html?id=5aee4d0f252941e1ae421b78a8ccbe60

https://learngis1.maps.arcgis.com/home/item.html?id=2eda03cbeec64e89a924cd9f9a1fad4b

my_first_map.save(webmap_properties)
traffic_map.save(webmap_properties)

gives an error

Sharing your full code would be beneficial.

I am having the exact same issue. Super frustrating.

@SB9 Did you ever resolve this?

Re: unable to save webmap from notebook

MichelleMarasco — Sat, 08 May 2021 17:33:33 GMT

@SB9 Just an update. I was able to resolve this by clicking the "restart the kernel, re-run the whole notebook" button at the top

Thanks MichelleMarasco. That works. I'm unsure why restarting the kernel is necessary, but it solved the problem.

Worked for me too!
