Failed to parse base64-encoded key: illegal base64 data at input byte 0

[crocokyle]

I'm attempting to run this in windows via docker-compose. I used the following commands to set the env vars:

set WG_ADMIN_PASSWORD="example"
set WG_WIREGUARD_PRIVATE_KEY="$(wg genkey)"

and here is the output I get:

Attaching to wg-access-server
wg-access-server    | time="2021-07-13T19:49:49Z" level=info msg="starting wireguard server on 0.0.0.0:51820" file="main.go:85"
wg-access-server    | time="2021-07-13T19:49:49Z" level=fatal msg="failed to load wireguard config: invalid wireguard config: bad private key: wgtypes: failed to parse base64-encoded key: illegal base64 data at input byte 0" file="main.go:96"
wg-access-server exited with code 1

I'm assuming this has something to do with line endings or the like, but not exactly sure how to troubleshoot this. Any help would be appreciated.
