Solution

From the above output, we see there is a syntax error at line number 4 and column number 0 and it says the property list is not terminated properly. Look at 3^rd line.

_id: ObjectId('5063114bd386d8fadbd6b009')

There is no “comma” after this property list item in the document or data object that you are trying to insert, try adding comma to solve “syntax error missing } after property list”. Hope it helped.
