Error in code for UndeterminedPercentageHandler

[maleasy]

When running checkQC on a MiSeq run, i get the following error:

Traceback (most recent call last):

When commenting out the handler in the config file it works:

...

#    warning: unknown
#    error: 9 # <% Phix on lane> + < value as %>

Possibly related: I tried to install checkqc 3.6.5 with conda, which seemed to work, but running checkQC lead to an error

ModuleNotFoundError: No module named 'interop'

conda however says that illumina-interop is installed.
I then installed checkQC with pip in a new, clean conda env, which worked, but shows the error described above.

Thanks for reporting, @maleasy ! I think this issue is caused by interop v1.1.10 not being supported in python 3.9. Support for that python version was added in this release https://github.com/Illumina/interop/releases/tag/v1.1.18. Until we solve this issue you should be able to run CheckQC in an environment with python 3.6 installed.

Thank you for your answer! I created a new conda env with python 3.6 and installed checkQC, which lead to the same ModuleNotFoundError for interop.
Installing with pip in a python 3.6 env works (but that already worked using python 3.9). The interop version is interop-1.1.23
CheckQC still throws the same KeyError exception as before.
