Geoserver importer NO_CRS task status doesn't trigger the CRS selection step

[giohappy]

When an invalid .prj file is sent to Geoserver the importer blocks in a PENDING status with the first task in NO_CRS status.
GeoNode's upload keeps returning the PENDING status but with an empty resume_url, which is expected to be populated to let the client redirect to the CRS selection (as with the srs step).

The result is a stale import that can only be deleted with the delete button (delete_url).

This was tested on master with this shepafile.
I suspect it also affects 3.3.x.

The problem is still there @afabiani. It can be reproduced on master with this sample tiff

@giohappy I don't think this one is related to this issue, or at least it does not depend from the Importer... I'll check
This is the error I get

I guess this is a side-effect of this one

[giohappy]

@afabiani I've tested the sample I attached both locally and master. Both cases I get the progress bar stuck and the importer session task[0] with NO_CRS.

[afabiani]

we should explictly send "mosaic=False" from the upload form

[giohappy]

No, we should assume mosaic False by default, not the reverse. Also considering that support for mosaic is a not well defined status right now.

[giohappy]

Found the difference. You were trying to upload the zip file, which triggers the mosaic workflow, because of the field.
I will open an issue for that, but when the tiff is loaded directly the problme of the progress stuck can be reproduced

EDIT: issue created #9097

[afabiani]

About the raster files, currently the workflow does not envisage passing through the srs_step, this is why it is not blocking...

[giohappy]

@afabiani either we support it, or we return an error in case the importer is stuck with an invalid CRS.

[afabiani]

yes, I agree @giohappy
