I'm having a problem reading a GeoJSON file in QGIS. The file can be found at this git repository. When I try to load in the file, I get an error message that it's invalid, but the "Reason:" field is empty. However, when I trivially reorder the fields under "geometry" to put

"type": "LineString"

at the start instead of at the end, QGIS can load it. The fixed version of the GeoJSON file is here. As far as I understand, the ordering of keys in a JSON object is completely immaterial, so I don't see why this change should make a difference. I'm able to read both files just fine in the web version of ArcGIS. Is this a problem with the GeoJSON file or have I found a bug in QGIS?

  • For original file, not able to reproduce using QGIS 3.6.2-Noosa on Ubuntu 18.04 64 bits as it works. => Version of QGIS you are using?

  • I'm using 3.6 but I've had this going back to older version, I'll try upgrading to 3.6.2.

  • Yes @user2856 please make that an answer and I'll accept. Thanks to your suggestion I've been able to reproduce the problem with gdal-2.3.2, 2.4.1, and 3.0, but I have no problem on gdal-2.1.4.

  • The problem is somehow related to crs. If I remove the whole crs member then GDAL 2.5-dev reads the json file without other edits.

It's not QGIS. It's the underlying GDAL library (I'm running 2.4).

Your 1st geojson fails when read from a file saved to the filesystem.

ogrinfo filepath/master/larsen_inflow.geojson # Fail
ogrinfo filepath/larsen-inflow branch/larsen_inflow.geojson  # Success

However... the 1st geojson can be opened fine when read from a url

ogrinfo https://<master>/larsen_inflow.geojson # Success!?!?
ogrinfo https://<larsen-inflow branch>/larsen_inflow.geojson  # Success

Smells like a bug to me. Suggest you ask on GDAL-DEV mailing list or post an issue (search for dupes first).

Edit: it's a bug and has been resolved.
