error while preprocessing landsat 9

[SHAYKE80]

Hello,
I get the following python error while trying to preprocess landsat. attached a screen shot of my definitions, followed by the error response:

An error has occurred while executing Python code:

TypeError: 'NoneType' object is not subscriptable

The above exception was the direct cause of the following exception:

Hello @SHAYKE80 , thank you for reporting this.
I'll look into it.

[semiautomaticgit]

I'm closing this because of the new version 8 of SCP.
Please reopen it if it is still relevant in the new version.
Thank you!
