If the created labels.json looks like this - then there is no "crs" that can be found.

{
"type": "FeatureCollection",
"name": "labels",
"features": [

]
}

to do: check whether this check is correct:

https://github.com/QGEP/qgepqwat2ili/blob/9c28c0ec463f26f3a83dff047e183dbf7ef0f90b/qgepqwat2ili/processing_algs/extractlabels_interlis.py#L173

 if labels_count == 0:
                continue
