QgsMessage Log

I would like to open pdfs via a url link within a feature layer in a docked window inside qgis by clicking on a link to a web hosted pdf I've tried: QWEB plugin lets you browse the web within a docked window but security protocols prevent pdfs from being shown.

I am working a plugin for QGIS, and I've run into an odd issue... My plugin opens and runs without errors, but the layers I am trying to create just don't show up. I tried using this method: viewshed_layer = QgsRasterLayer(viewshed_raster, "Viewshed") if viewshed_layer.isValid(): QgsProject.instance().addMapLayer(viewshed_layer) else: error_msg = "Failed to load viewshed.tif" QgsMessageLog.logMessage(error_msg, "ViewDrone", QgsMessageLog.ERROR) Is that wrong? Or should I look for other errors?

I am currently working on developing a plugin for QGIS and I keep on running into the same error related to the GDAL command ViewshedGenerate. I've tried multiple different solutions (including setting creationOptions = ['None'] as proposed in a question about a similar error) but so far nothing is working. I've left some of the methods I've tried as comments in the code.
