Sentinel-3 pre-processing graph on SNAP 9

Hi,
I’m working on the estimate of evapotranspiration and I’m currently stuck on pre-processing of Sentinel-3 data (chapter 3.3.1.9 of UM v1.1.0).
The problems are in Graph Builder.

Setup
  • Windows 10 Pro 22H2
  • SNAP 9
  • Sen-ET SNAP plugin v1.0.0
  • auxdata from Github repository, commit 247375f on Jun 8, 2022
  • S3A_SL_2_LST____20221217T094311_20221217T094611_20221218T185045_0179_093_193_2160_PS1_O_NT_004.SEN3 downloaded with SEN_ET > Download sentinel data plugin. (I have also tried others data with same results)
Problem 1

When I try to load the graph sentinel_3_pre_processing.xml with File > Load Graph I receive this error:

Unable to load graph java.ioFileInputStream@2cfab1f7
java.lang.IllegalArgumentException: geoRegion

Problem 2

The graph is correctly loaded if I replace the value of the line 36 <geoRegion>!INPUT_AOI_WKT!</geoRegion> with the corresponding value copied from the file map.wkt (generated by the online tool geojson.io), but when I try to click on Run button, I receive this error:

Error: Invalid number of points in LinearRing (found 3 - must be 0 or >= 4)
map.wkt

Could you please help me?
Thank you.
