      Problem Statement/Rationale

      mongoimport fails when importing an empty JSON array, and emits an error. Instead, it should successfully import 0 records and exit.

      Steps to Reproduce

      1. Create file empty-json-array.json, with contents []
      2. Replace placeholders as appropriate, then run:
         
        mongoimport --uri <uri> --db <db> --collection <collection> --type json --jsonArray --file empty-json-array.json

         

        Expected Results

      A successful import with no errors reported

      Actual Results

      Failed: error processing document #1: invalid character ']' looking for beginning of value

      Additional Notes

      Version:

      mongoimport version: 100.7.0
      git version: 17946f45f5fabfcdd99f8960b9109f976d370631
      Go version: go1.19.3
         os: linux
         arch: amd64
         compiler: gc 

      Solution

      We will make mongoimport accept a file with an empty JSON array in it. When it encounters such a file, it will log a message saying that this file will be skipped because it does not contain any documents. This message will be logged at the Info level.
