Error Sentinel-2 Pre-Processing Graph

snap Sen-ET
#1

Hello,
While i’m trying to create the pre processing graph from sentinel-2 images there are some error messages i’m constantly having as ‘‘the naming convention structure is invalid for input file’’ (1)(while i’m loading the .txt file that i’ve manually generated from the copy of pre processing graph .txt file of snap’s original, with replacing the lines that marked with ‘’!’’) and ‘‘graph exception error’’ (2) are including ones. I’ve check the formats of naming conventions from https://sentinel.esa.int/web/sentinel/user-guides/sentinel-2-msi/naming-convention of the sentinel-2 images that i’ve downloaded both from earth explorer and sci-hub but probably the error is not caused by this. Additionally, with the different images that sensed different times from same sources, i could created the pre processing graph without any problem. So i’d like to ask what would be the reason of the diffrences of these results.
The error messages i got are attached below with the numbers i used, respectively.

The scenes where you observe this issues, are they old or very new?
It seems they cannot be read by the product reader in SNAP.
Which version of SNAP are you using? Have you updated to the latest?
It could be that the download didn’t work well. Especially if some scenes work and others not.

Maybe this post helps you: SNAP 8.0 released

Hi,

I have the same problem (Error: org.esa.snap.core.gpf.graph.GraphException) and I can’t run the Graph Builder: sentinel_2_pre_processing.xml.
This is a new scene from 2021-10-28.
I am using the latest version of SNAP: 8.0.8.
I can open my product as RGB in SNAP.
I downloaded the product manually using CREODIAS.

Solution: Just fill all the inputs and click RUN, the Error will disappear.
