Unexpected JSON data scrolling when running first Index

I've just set this up, and the test procedure responds with all OK's, so I think I've got everything right.

What I am noticing is a bunch of scrolling, for what I'm assuming are documents that it cannot index based on the .ext of the files.

Is this normal? Something that could be filtered out?
Looks like .bmp, exe, dll, smb, 001, 002 extensions and more. I haven't seen any for anything I would expect fulltext to actually index.

After a bit of running that, it seems to go back to those files and then the "extra output" at the bottom turns to:

{"reqId":"NLvNcoNvZDOz2w6NH74M","level":0,"time":"2021-07-20T17:56:12+00:00","remoteAddr":"","user":"--","app":"files_fulltextsearch","method":"","url":"--","message":"[debug] fillIndexDocument request -- {\"document\":{\"id\":\"6699459\",\"providerId\":\"files\",\"access\":{\"ownerId\":\"\",\"viewerId\":\"\",\"users\":[],\"groups\":[],\"circles\":[],\"links\":[]},\"modifiedTime\":1281935414,\"title\":\"\",\"link\":\"\",\"index\":{\"ownerId\":\"\",\"providerId\":\"files\",\"source\":\"\",\"documentId\":\"6699459\",\"lastIndex\":1626803730,\"errors\":[],\"errorCount\":0,\"status\":28,\"options\":[]},\"source\":\"files_group_folders\",\"info\":[],\"hash\":\"\",\"contentSize\":0,\"tags\":[],\"metatags\":[],\"subtags\":[],\"more\":[],\"excerpts\":[],\"score\":\"\"}}","userAgent":"--","version":"21.0.3.1"}

Help is appreciated. It almost seems like there is some debug output that is turned on.

No source files or tests are named. Start by reproducing the first Index with the listed .bmp, .exe, .dll, .smb, .001, and .002 files, then inspect the fulltextsearch indexing logs and debug configuration. Done means determining whether this output is expected and identifying a specific change needed to suppress unsupported-file or debug messages.
