get_leaflet_tile_layer error (v0.3.13)

[giswqs]

Both v0.3.13 and the GitHub source throws the same error when using the example. v0.3.12 works fine.

from localtileserver import get_leaflet_tile_layer, TileClient
from ipyleaflet import Map

# First, create a tile server from local raster file
tile_client = TileClient('~/Downloads/dem.tif')

# Create ipyleaflet tile layer from that server
t = get_leaflet_tile_layer(tile_client)

# Create ipyleaflet map, add tile layer, and display
m = Map(center=tile_client.center())
m.add_layer(t)
m

v0.3.13

v0.3.12

[banesullivan]

Is this Python 3.6?

[giswqs]

It is Python 3.8. You can see the Python path in the error screenshot.

Can you share a report

import localtileserver
print(localtileserver.Report())

[giswqs]

Everything works fine when I downgraded localtileserver to v0.3.12.

Sorry, can you actually share the whole env? With either pip list or conda list. I need info on traitlets which isn't covered in the report

[giswqs]

Sorry for the long list. My env has a long history.

[banesullivan]

I think the issue is that the change I introduced requires traitlets > v5. I'll see how I can fix this to be compatible with traitlets v4

[banesullivan]

Fix is here: ipython/traitlets#626 (comment)

[giswqs]

I just upgraded traitlets to v5.1.1, and the problem is solved. The traitlets package in my env was probably installed years ago. I have not used it directly.
