It looks like there is the bug for butler to get the raw exposure data in lsst_distrib: w_2020_06. This bug did not happen in w_2020_04. The following is the test data: input.zip
I use the followings to try to get the raw data:
The following is the error message (You can also see details in errorMsg.txt):
It looks like the dataset type becomes "raw_amp" even though I use "raw" in the get().
The followins is the data ID of "raw" if I use butler.getKeys("raw"):
There should be no 'channel' because it is not "raw_amp".
