Bug: Any occurrence of BC-tag-note breaks Breadcrumbs Indexing.

[chrisgrieser]

Describe the bug
Note sure when exactly this started to occur, but I noticed that any use of BC-tag-note will break down Breadcrumbs Indexing. As a result, all up and down are messed up or missing.

Removing BC-tag-note: '#tag' only leads to the next note with such yaml to throw an error... 😦 with the respective tag. Removing all BC-tag-note in my vault seems to fix the issue.

Actually, due to a bug with the metadata extractor, I figured out that the problem seems to be caused by a file that I use as custom dictionary for the various complements plugin for autocompletion of citekeys. The file looks like this (only a few thousand lines longer) and does not have any yaml header.

potentially this solves the problem? kometenstaub/metadata-extractor#17 (comment)

[SkepticMystic]

@chrisgrieser, I read over the thread in metadata-extractor. It seems to be an Obsidian issue then?

[chrisgrieser]

Not sure, maybe @kometenstaub can answer this better?

[kometenstaub]

I needed to check for both undefined and null. It's not typed like that in the API, but the null type in it means that it can return something else than what is expected.
So

if (someObject)

instead of

if (someObject !== null)

should be used.
