Hi
I am trying to carry out the lecture instruction and stuck at this step
https://university.mongodb.com/mercury/M103/2020_March_10/chapter/Chapter_1_The_Mongod/lesson/5a974352c9d4ec11e704edd6/lecture
Tried at this step Use mongodump to get a BSON dump of a MongoDB collection:
mongodump --port 30000 --db applicationData --collection products
it gave me error
Failed: error counting applicationData.: Invalid namespace specified ‘applicationData.’
then I look at the video and follow the command as per the video
vagrant@m103:~$ mongodump --port 30000 -u “m103-admin” -p “m103-pass” --authenticationDatabase “admin” --db exampleDB --collection students
I had error message as below
2020-03-27T12:35:49.245+0000 Failed: error connecting to db server: server returned error on SASL authentication step: Authentication failed.
What is actually going wrong?
