@kylefelipe, thanks for reporting. Does the output of the commands
from qgis.core import QgsProviderRegistry
print(QgsProviderRegistry.instance().providerList())
added just before the mesh_layer = QgsMeshLayer(mesh_path, "mesh", "mdal")
contain the mdal
provider name?
Does the output of print(mesh_layer)
added just after mesh_layer = QgsMeshLayer(mesh_path, "mesh", "mdal")
states that it is a valid layer?
In order to avoid the error
File "C:\OSGeo4W_V2_8/apps/qgis/python/plugins\processing\core\Processing.py", line 231, in runAlgorithm
raise QgsProcessingException(msg)
_core.QgsProcessingException: There were errors executing the algorithm.
you need to put the QgsApplication.processingRegistry().addProvider(QgsNativeAlgorithms())
after the Processing.initialize()
line, not before. Anyway, QgsApplication.processingRegistry().addProvider(QgsNativeAlgorithms())
is not needed.
Hi @agiudiceandrea, thx for helping me!
print(QgsProviderRegistry.instance().providerList()) added just before the
mesh_layer = QgsMeshLayer(mesh_path, "mesh", "mdal")
contain themdal
provider name?
R: No, just show these names
['arcgisvectortileservice', 'cesiumtiles', 'copc', 'ept', 'gdal', 'mbtilesvectortiles', 'memory', 'mesh_memory', 'ogr', 'tiledscene', 'vectortile', 'vpc', 'vtpkvectortiles', 'xyzvectortiles']
Does the output of
print(mesh_layer)
added just aftermesh_layer = QgsMeshLayer(mesh_path, "mesh", "mdal")
states that it is a valid layer?
R) No, it shows that is an invalid layer
you need to put the
QgsApplication.processingRegistry().addProvider(QgsNativeAlgorithms())
after theProcessing.initialize()
line, not before. Anyway,QgsApplication.processingRegistry().addProvider(QgsNativeAlgorithms())
is not needed.
R) Thx.
I am updating the gist with new code...
And its still issuing (...) There where errors executing the algorithm

I am updating the gist with new code...
Does the new code make QgsProviderRegistry.instance().providerList()
contain the mdal provider name and mesh_layer be a valid mesh layer? What is the full error message?

No...

Any updates on that? Im running into the same issue.
What is the bug or the crash?

Additional context
Runing meshexporttimeseries from GUI works like a charm. STEPS:
Add the .nc file as Mesh layer to project Set mesh projection to ESPG:4326 Add the gpkg as vector layer to project Go to Toolbox> Double click on Export time series values from points of a mesh dataset Input mesh layere > Choose mesh layer above Data set groups > Click on
...
thenSelect in available dataset groups
thenselect all
>ok
Ending time > choose the last one (press end on keyboard) Points for data export > Choose pont layer Digits count for coordinates > 8 Digits count for dataset value > 8 exported data csv file > choose path and file name clickrun
