Hello,
I may have come across a problem with the JSON Output from the InSAR-Overview operator when run from GPT.
I created a short graph consisting of ProductSet-Reader and InSAR-Overview (as described in the online help for InSAR-Overview). When running the graph using gpt:
gpt insar_overview.xml -Pfilelist=S1A_IW_SLC__1SDV_20210404T050204_20210404T050231_037296_0464E1_ECD3.zip,S1A_IW_SLC__1SDV_20210416T050204_20210416T050231_037471_046AEE_08BF.zip,S1A_IW_SLC__1SDV_20210428T050205_20210428T050232_037646_0470FF_7B48.zip -Pjson_file=test.json
I get the following output in test.json:

The identified reference scene is the same as in the GUI (Stack Overview). The insar_overview in secondary also seems to be ok but the product_name, orbit etc. are all the same as in reference.
Also in the example JSON output in the online help article product_name is the same in secondary and in reference.
I am using SNAP Microwave Toolbox 11.0.1.
