interface {} is nil, not string

[hubsmoke]

Hi, I am attempting to set up a fresh IPFS node to point to S3 storage using this plugin

I have followed the instructions and have tried various combinations of things and have finally gotten the IPFS daemon to run, but I now have the following error:

go-ipfs version: 0.10.0-dev-f63a997c3-dirty
Repo version: 11
System version: amd64/linux
Golang version: go1.17
panic: interface conversion: interface {} is nil, not string
