Figure generation with Docker version

[grennfp]

Dear locuscompare2 authors,

Thank you for providing this useful tool!

I have been trying out the Docker version you provided so that I may use this tool with custom eQTL statistics and GWAS data that is not available on the website.
I tried it out on a subset of my data (containing significant eQTLs and GWAS signals), just with coloc and fastenloc tools. I do get output from the tools themselves, but it seems I am unable to get the tool to generate any figures due to this error.
I was wondering if you had any suggestions on a workaround? Here is the error message:

I've tried running with multiple configs for multiple eQTLs/tissues in one run but receive a similar error.
