6 years ago Thanks for the bug report. This seems like it is a satpy error and in the future this is probably better on the satpy repository. Anyway...
Could you try running at the top of your code from satpy.utils import debug_on; debug_on() and running your code again and pasting the output here. The error message you got (which I thought I had cleaned up) is saying that the true_color composite wasn't created. The debug messages should show you why.
It's possible satpy is looking for more than just C01, C02, and C03 data, but I can't think of a reason why.

This is the code I'm using
Problem description
I'm trying to generate a corrected true color images from GOES-16 netcdf files available en AWS. I tried the example gave for Himawari-8 (https://github.com/pytroll/pytroll-examples/blob/master/satpy/ahi_true_color_pyspectral.ipynb). First, I couldn't use find_files_and_readers, so I define the filenames by myself. No problem on that.
Second, I couldn't process full disk image because of memory lack, I'm running the code in a 16GB RAM and 12 core server. Then I tried to process just South America. I used area definition from this web https://github.com/pytroll/satpy/blob/master/satpy/etc/areas.def
I got the following error:
Traceback (most recent call last): File "true_pytroll.py", line 28, in

Thank you very much.
