UnboundLocalError: local variable 'response' referenced before assignment

[gwfami2]

Hi,

Any ideas? I just attempted to use the ORS Tools in QGIS and received the following error:

Traceback (most recent call last):
File “/Users/xxx/Library/Application Support/QGIS/QGIS3/profiles/default/python/plugins/ORStools/proc/matrix_proc.py”, line 275, in processAlgorithm
duration = response[‘durations’][s][d]
UnboundLocalError: local variable ‘response’ referenced before assignment

Here is the log from the failed execution:

Looking at the error it seems that the plugin sees that there is missing geometry in the point layer. Can you try it with a different point file and see if that works as that will help work out if it is a data problem?

[gwfami2]

Hi,
I tried it with a totally separate point file that I created today. It’s experiencing exactly the same error.

Seems like you’re having invalid geometries in your shapefile… Try a „Repair geometries“ from the Toolbox.

[gwfami2]

I must be pretty slow. I repaired the geometries, converted them back to points from multipoints, then reran the matrix tool. Still doesn’t work.

Due to the size of the logfile, I had to upload it to google drive. Here’s a link to it, as well as the point shapefile.

The log file appears to be returning html for a web page, very weird.

log file and point shape file

Update: I removed the first part of the logfile and saved it as an html file and it is returning a web page.

What’s the URL you’re using? Just paste the full log message in the ORS Tools GUI, incl URL and parameters.

[gwfami2]

The ORS Tools GUI doesn’t have a matrix option, I’m running it from the processing toolbox.

Ok,
I managed to pull the ORS Tools log for QGIS, this is what it has.

[nils]

Yeah, wrong URL. You’re missing the “api.” after “https”.

[gwfami2]

Thanks, that fixed not only this problem but a host of others as well.
