I'm attempting to use gortr with pre-packaged octorpki (installed Debian octorpki package, but there's no corresponding debian gortr package available).

Built gortr from git clone.

Trying to launch gortr with the following command line:
gortr-v0.14.8-5-g9f01dca-linux-x86_64 -tls.bind 127.0.0.1:8282 --cache http://127.0.0.1:9880/output.json -log.verbose -verify=false

(I have verified that octorpki is providing the desired output at the URL specified with CURL).

I get the following results:
INFO[0002] New update (474511 uniques, 474511 total prefixes). 0 bytes. Updating sha256 hash -> b147e7168f42d0146c81dad91fe428faf33735b6efa6e18b72bd041bad3eb885
INFO[0004] Updated added, new serial 0
FATA[0004] open : no such file or directory

Everything seems as I would expect except for the sudden and useless (in terms of information) error at the end, which causes garter to exit almost immediately after it has started.

I have no idea what file it's attempting to open or where or for what purpose and the error provides no hints.
