error while using docker image (andersenlab/vcf-kit:20200822175018b7b60d: TypeError: a bytes-like object is required, not 'str'

[laura-bankers]

Hello - I am receiving the following error using the latest docker image (andersenlab/vcf-kit:20200822175018b7b60d). Any idea what this means or what I need to do to fix it? Any help you can provide is much appreciated.

Error:
Traceback (most recent call last):
File "/opt/conda/envs/vcf-kit/lib/python3.7/site-packages/vcfkit/vcf2tsv.py", line 89, in
line = line.replace("u'","") # No idea why u' is prefixed...
TypeError: a bytes-like object is required, not 'str'

Seems like an encoding problem (also evidenced by the "u" prefix that the developer mentions).

A quick fix would be to decode the string by replacing:
line = line.replace("u'","")
with
line = line.decode().replace("u'","")
in the file /opt/conda/envs/vcf-kit/lib/python3.7/site-packages/vcfkit/vcf2tsv.py.

Bear in mind that this change will likely not survive updates to the docker image or conda environment.
