E432: Tags file not sorted: tags

[bz-stripe]

Seeing an error when I tab complete:

Scanning tags.
E432: Tags file not sorted: tags
Press ENTER or type command to continue

I'm generating tags with GutenTags, with these configs

"" Gutentag
set statusline+=%{gutentags#statusline()}
let g:gutentags_add_default_project_roots = 0
let g:gutentags_project_root = ['package.json', '.git']
let g:gutentags_cache_dir = expand('~/.cache/vim/ctags/')
let g:gutentags_generate_on_new = 1

let g:gutentags_generate_on_write = 1
let g:gutentags_generate_on_empty_buffer = 0

I'm not sure what this has to do with supertab.
