I have updated SNAP4.0 to SNAP5.0 and Sen2Cor2.2.1 to Sen2Cor2.3.0 according to the ‘S2 MPC’(2016-11-25). Then I conducted the AC in the Anaconda window. When it was finished , something wrong happened. You can see the Error message in the picture above. I upload the error report. I guess there is something wrong with the B8(B8A) name.

I don’t know how to deal with the problem, who can help me ?
Thank you !

This has already been reported here:

• Sen2cor: KeyError: 'gfs'
• Sen2Cor - Metadata file is invalid
• Sen2cor metadata validation throwing errors

The issue appears to be yet unsolved.
