broken featurelayer when using Arcgis 4.9

[馬修胡1]

Hi, I got a problem when I loading a Featurelayer from my GIS server with ArcGIS JS 4.9, and it will be broken on my Map.

The following picture is the broken Featurelayer.

But when I go back to use 4.8, it returned to normal. like this:

This problem has been bothering me for a long time.

Does anyone know how to solve it?

Thanks in advance!

PS: Sorry for my poor English : P

This is a bug with 4.9 you will need to roll back to 4.8 and wait for 4.9 to fix this issue. There has been workaround reported.
