[MapServer-users] Error advises checking logs, but I am not sure what logs it's referring to

[Rob Dennett]

I got an error trying to run that command:

ERROR 4: Only read-only mode is supported for /vsicurl

When I ran duckdb at the command line, I was able to run

Select geometry from read_parquet("github.com/iamgeodude/testgio/raw/main/area_types.parquet")

Just fine.  Updating the code from geom to geometry in the .map file yields the same error.  Are the logs mentioned referring to the error_log I am looking at, or something else?

Thanks

Looking at the file, the layer name is plural, area_types and the
geometry column is 'geometry' not 'geom'.

Run the following from the command line and see what errors you get:

ogrinfo -sql "select geometry from area_types"
/vsicurl/https://github.com/iamgeodude/testgio/raw/main/area_types.parquet
