Python error QGIS 3.12

[myfta]

Hi, I am using QGIS 3.12 and the latest version of qgis2web (3.13.0).

The OpenLayers version works but when I switch to Leaflet (which I want to use) just clicking "Update Preview" throws a Python error.

Please advise. Thanks.

One of your layers is using a style which qgis2web is not handling. Can you narrow your project down to a single layer which shows this error, and then upload that layer and your project file to this thread?

Hi,

I have done the testing as you hinted. I have discovered that one of my layers was using "Point cluster" for the Symbology. If I revert that to "Rule-based" the leaflet option works.

Happy to send the project if you still need it.

Thanks.

Thanks for the info - no, I don't need your files now. Yo uknow you can select "Cluster" within qgis2web? That should go some way to producing what you want. There is an open issue here to get rid of the qgis2web "Cluster" option, and instead activate it when the cluster renderer is selected:

https://github.com/tomchadwin/qgis2web/issues/377

I'll therefore close this issue, but thanks for reminding me of #377.

Hi thanks for this great tool. I seem to be having a similar problem also but here is my error code. I have multi-geometry in my KML file that is loaded as 1 layer. I tried deleting that layer and QGIS2web worked. This issue is, I want to include this layer as this is the basis and purpose of my project. In google earth, you can split apart multi-point geometry, I am trying this but have to test it more.
