Restoring from BSON dump breaks when directory contains metadata files created by mongodump

[cdxOo]

By default recent versions of mongodump create metadata files in the form of .metadata.json within the dump diretory. Theese files are not filtered and therefor restore breaks when tying to deserialize them as bson.

I suggest checking for !(/\.metadata\.json$/).test(docName) in fromJSON() before processing them further.

I'm not sure if this is related but I get the following stacktrace from a fresh dump using mongodump:

❯ tree mongo-seed/dump

I'm using mongo:3.4-jessie docker image.

Edit: I deleted MyDummyCollection.metadata.json but it's still failing with the same error.
