Description

I am trying to use an online CSV file and plot its content as points using a Processing model. These steps causes a Python error:

1) Open a new model
2) Add the algorithm for downloading a file. I used https://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/4.5_day.csv.
3) Add the algorithm for creating points from a table and configure it
4) Run the model
5) I now get this error message:

Traceback (most recent call last):
File "C:/PROGRA~1/GIS/QGIS/apps/qgis/./python/plugins\processing\algs\qgis\PointsLayerFromTable.py", line 91, in processAlgorithm
raise QgsProcessingException(self.invalidSourceError(parameters, self.INPUT))

Ett fel uppstod vid körning av Skapa punktlager från tabell

Ett fel uppstod vid körning av Skapa punktlager från tabell

Beräkningen misslyckades efter 0.38 sekunder

I expected the data from the download algorithm to be available for other algorithms. Is this incorrect or is this a bug?

Have you tried providing a file name to the downloader, I'm not sure if the file can be properly set in memory and converted to an output.
