Just starting to use the Cloud product. After updating a point’s attribute value in the Android app, I pushed the “Publish changes” button. On the server I see a job of type “Delta Apply”. The status goes from Pending to Failed. Tried it a few times with the same result. The log has this: Start QGIS Application 18:32:07.148 QGSSTDERR INFO Starting QGIS app version 32601 (exported)… 18:32:07.154 QGSSTDERR WARNING QStandardPaths: XDG\_RUNTIME\_DIR not set, defaulting to ‘/tmp/runtime-root’ Download Project Directory 18:32:10.127 root INFO Downloading file “Parcels\_MASTER-wgs84.dbf”… 18:32:11.096 root INFO Downloading file “Parcels\_MASTER-wgs84.shp”… 18:32:11.835 root INFO Downloading file “Parcels\_MASTER-wgs84.shx”… 18:32:12.311 root INFO Downloading file “PastTrees.dbf”… 18:32:13.000 root INFO Downloading file “PastTrees.shp”… 18:32:13.479 root INFO Downloading file “PastTrees.shx”… 18:32:14.268 root INFO Downloading file “Roadsdraft-1-wgs84.dbf”… 18:32:14.802 root INFO Downloading file “Roadsdraft-1-wgs84.shp”… 18:32:15.322 root INFO Downloading file “Roadsdraft-1-wgs84.shx”… 18:32:16.090 root INFO Downloading file “Trees-wgs84 2021.kmz”… 18:32:16.618 root INFO Downloading file “Trees-wgs84.dbf”… 18:32:17.173 root INFO Downloading file “Trees-wgs84.shp”… 18:32:17.734 root INFO Downloading file “Trees-wgs84.shx”… 18:32:18.248 root INFO Downloading file “Trees.qgz”… 18:32:18.746 root INFO Downloading file “tree zones.dbf”… 18:32:19.249 root INFO Downloading file “tree zones.shp”… 18:32:20.089 root INFO Downloading file “tree zones.shx”… 18:32:20.121 root INFO Local files list for project “e7b4985b-afde-4e9f-8ac2-c8ca0e7be0d5”: Name Size MD5 Checksum * * * Parcels\_MASTER-wgs84.dbf 3460550 9362ad2e371f65cae5ddd34ba3ec48e2 Parcels\_MASTER-wgs84.shp 1031080 1db7e5f65ee39319ff4b18f2e28c4596 Parcels\_MASTER-wgs84.shx 36316 1ce48886ca9cc6965b58aa0fc185c1f8 PastTrees.dbf 199039 200223a9ddd158a983fd191b6f08cb2e PastTrees.shp 18664 ee2f040249a906b046c4a560eb0f4537 PastTrees.shx 5404 394a9af54214febe273e354f09d7e34b Roadsdraft-1-wgs84.dbf 168109 91ab5ff2a95587cc9cbf3bddae6740cd Roadsdraft-1-wgs84.shp 171340 ac5d1aa8fbe323182f2de0f707a11118 Roadsdraft-1-wgs84.shx 4124 1290bb3e0c2c33c5b949c4529daaf8e4 Trees-wgs84 2021.kmz 77711 c0f77c67180283bfe8891f8ac24c295e Trees-wgs84.dbf 803318 fcd23cced4d810461659311a4bca56a2 Trees-wgs84.shp 75252 4b0bcac285f3dc0dca86e1dc3ba8ef20 Trees-wgs84.shx 21572 6125fa9129608bf16f1e3ec9a3c97de0 Trees.qgz 46328 c7d7099324742c7b2b5c1bd5c475385e tree zones.dbf 120 54e0f18fefe5e368b8e2590d0caa262d tree zones.shp 924 198aeca799c2426bbcfc30da9a7a0ebd tree zones.shx 140 7a09683bb44d72acb9e8a3017b4bc487 Apply Deltas 18:32:20.122 root INFO Loading project file “/tmp/tmpp7dzy162/files/Trees.qgz”… proj\_create: Error -38: failed to load datum shift file proj\_create: Error -38: failed to load datum shift file 18:32:20.784 root INFO Loading delta file “/io/deltafile.json”… 18:32:20.809 qfieldcloud.qgis.apply\_deltas ERROR An unknown error has been encountered while applying delta: 18:32:20.814 QGSSTDERR WARNING QFSFileEngine::open: No file name specified 18:32:20.814 QGSSTDERR INFO Stopping QGIS app… * * * _Imported from [GitHub discussion](https://github.com/opengisch/qfield/discussions/3348) by @bbkofman on 2022-09-16T18:48:31Z_ ---

If you are using experimental data sources, Shapefiles in your case, please make sure you follow the requirements as described here: [Get Started - QField Ecosystem Documentation](https://docs.qfield.org/get-started/tutorials/get-started-qfc/?h=shapefile#configure-your-project-layers-for-qfield) . Even better - just use geopackages. * * * _Imported from [GitHub comment](https://github.com/opengisch/QField/discussions/3348#discussioncomment-3665570) by @suricactus on 2022-09-16T20:16:14Z_ ---
