WCST_Import error index out of range with recipe "wcs_extract"

Component: wcst_import Version: development

Complexity: Medium


I tried to ingest a coverage with recipe "wcs_extract" from local petascope with recipe ( coverage does exist in petascope named "mean_summerair_temp" ).

  "config": {
    "service_url": "http://localhost:8088/rasdaman/ows",
    "tmp_directory": "/tmp/",
    "crs_resolver": "http://localhost:8080/def/",
    "default_crs": "http://localhost:8080/def/crs/EPSG/0/4326",
    "mock": false,
    "automated": true,
    "subset_correction" : false
  "input": {
    "coverage_id": "NIR2323"
  "recipe": {
    "name": "wcs_extract",
    "options": {
      "coverage_id": "mean_summerair_temp",
      "wcs_endpoint" : "http://localhost:8088/rasdaman/ows/wcs",
      "partitioning_scheme" : [2720, 2361],
      "tiling": "ALIGNED [0:2000, 0:2000]"

and it returns error

It seems the coverage does not have a CRS somehow. Could you attach the DescribeCoverage? oputput? http://localhost:8088/rasdaman/ows/wcs?service=WCS&version=2.0.1&coverageId=mean_summerair_temp

Yes, I've attached it in here http://rasdaman.org/attachment/ticket/1199/mean_summer_airtemp.xml but I think it is another problem as this is imported by system_test.

Very weird, I don't see how that xpath could fail with that coverage, I will check in more detail at one point, thanks for reporting

I've tested it and I think the problem is as you suggested (almost right) from wcs_endpoint. There is 2 cases of these problem:

+ If wcs_endpoint does not exist, example: http://localhost:8088/rasdaman/ows (my local is http://localhost:8088/petascope/ows )
+ If wcs_endpoint does exist but coverage_id does not exist: mean_summerair_temp (instead of mean_summer_airtemp).

So need to check wcs_endpoint first and then check coverage_id does exist. I can do it if you think it is not difficult. Thanks.

  • Priority changed from major to minor

Ok, glad to confirm that this throws an error only when the input is wrong. We indeed need to provide the user with a better message but not critical right now. I've set priority to minor, maybe we can do it when there's a bit more time.

Alex, it has been done in code review and wait for you and Vlad. I'm reading ticket 1188 (test WCPS 2.0 requirement and doing it now), Thanks.
