Dear all, thanks :)

Carlo Ruiz,

Actually, in my case, the input should be shapefile and the outputs
gtiff,png and kml.

Great! I changed to v 1.3.0 too

this is my new url request:

http://172.17.0.2/?map=/maps/dengue-Rio-de-Janeiro.map&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&LAYERS=RIO_DE_JANEIRO&STYLES=&CRS=CRS:84&BBOX=-43.7965385309,-23.0828926973,-43.0990394004,-22.7460202858&WIDTH=400&HEIGHT=300&FORMAT=kml

> Do you have KML in the list?

yes. Full GetCapabilities xml here: https://pastebin.com/z2myYc5m

> Did you just guess or is there somewhere wrong documentation about
metadata item you have tried # "wms_format" "image/png")

I saw it at some page ... but I think I haven't seen any difference (I
don't remember so well) .. so I commented this option.

> However, you must explicitly add KML into WMS outputformats in the
metadata. It seems that you have played with it because you have this line
commented out:

OK .. I added `wms_getmap_formatlist` parameter. I also added
`wms_formatlist` to metadata layer

I also change SRS=EPSG:4326 to CRS=CRS:84

Seth,

I also added crs:84 .. but the result is the same ..

KML by specification uses only a single projection, EPSG:4326 (
http://www.gdal.org/drv_kml.html)

My shapefile is defined as epsg:4326 too

The png output works fine ... maybe something in kml conversion is doing
wrong ...

The log about kml request is here: https://pastebin.com/iP4h0wXx
