While running the command certspotter -start_at_end the following error is thrown:

certspotter: error while monitoring https://nessie2025.ct.digicert.com/log/: error loading STHs directory: error parsing /home/user/.certspotter/logs/5tIxY0B3jMEQQQbXcbnOwdJA9paEhvu6hzId_R43jlA/unverified_sths/409141520-pCGVtdnf7gX3Sb-BXo7-U8sYlLNH_2sBH-i9S62Ak88.json: unexpected end of JSON input

Running certspotter just after new installation, the above error is thrown.

What are the contents of /home/user/.certspotter/logs/5tIxY0B3jMEQQQbXcbnOwdJA9paEhvu6hzId_R43jlA/unverified_sths/409141520-pCGVtdnf7gX3Sb-BXo7-U8sYlLNH_2sBH-i9S62Ak88.json?

It is empty.

Did your system have an unclean shutdown while running certspotter?

If you remove /home/user/.certspotter/logs/5tIxY0B3jMEQQQbXcbnOwdJA9paEhvu6hzId_R43jlA/unverified_sths/409141520-pCGVtdnf7gX3Sb-BXo7-U8sYlLNH_2sBH-i9S62Ak88.json and re-run certspotter, does the error happen again?

I am not sure, I had a unclean shutdown (which could have probably happened). But cerspotter is successfully running after I removed that file, and restarted it.
