MongoDB error: mongoexport or mongodump Unrecognized field snapshot


Failed: error writing data for collection to disk: error reading collection: Failed to parse: { find: “ProductMmsg”, skip: 0, snapshot: true, $readPreference: { mode: “secondaryPreferred” }, $db: “XYZ” }. Unrecognized field ‘snapshot’.

Reason for error:

This usually happens due to different versions between mongodump or mongoexport vs your MongoDB server. For example, you are exporting or dumping using version 3.6 and your MongoDB server is on version 4.0

Possible solution of this error:

First, the solution is to use the same version as the version of your MongoDB server.

Second, the solution is used –forceTableScan in your command

mongodump --forceTableScan -d database_name -o target_directory

Also Read : Start & Stop Mongo DB Server

mongoexport --forceTableScan -d dbname -o Mongo.json

Starting with MongoDB 4.4, the MongoDB Database Tools are now released separately from the MongoDB Server and use their own versioning, with an initial version of 100.0.0. Previously, these tools were released alongside the MongoDB Server and used matching versioning.


If you are using MongoDB 4.4+ then mongodump, mongoexport, mongorestore will not available with MongoDB server installation you need to download the mongo tool separately.
