MapServer Error

[WKiehn]

Hi,

with the version Alteryx Designer 2020.3.5.30242 we get an error, if we are using a custom map for the background with the projection EPSG3857. 

We solved it by replacing the EPSG statement with original projection parameters.

Please can you check, if the projection is missing in the corresponding reference list. With version 2020.2.3 the maps were still displayed without errors.

Thanks,

Werner

Hi @WKiehn 

Would you mind also forwarding this over to support@alteryx.com please? Thank you for bringing this to our attention

We fixed and solved it and thank the support team for their help.

If you have installed Alteryx and GIS programs, such as QGIS, it can happen that the MapServer doesn't find the projection files and thus produces various errors.
In order for MapServer to access the correct files, the following system environment variable must be set:
PROJ_LIB
For the Admin installation with the path:
C:\Program Files\Alteryx\bin\RuntimeData\Projections\nad
And for the non-admin installation with the path:
C:\Users\user\AppData\Local\Alteryx\bin\RuntimeData\Projections\nad

Is it possible to install the system environment variables directly with Alteryx in the future?
