Compass fails to import a JSON file that can be imported with no issues with mongoimport

XMLWordPrintableJSON

    • Type: Bug
    • Resolution: Won't Fix
    • Priority: Major - P3
    • None
    • Affects Version/s: 1.17.0

      When I try to attach the file in question, Compass inserts some of the documents but then quickly fails with "Unexpected end of JSON input".

      At the same time, this file can be imported with no issues with mongoimport:

      To add more to it, if, after loading data with mongoimport, I export it with Compass, then the Compass will fail to load the data that was just exported back into the MongoDB instance. The error is the same - "Unexpected end of JSON import".

      Tested against MongoDB v4.0.9.
