Copying a entire database to other host with secondary preferred gets index error

Hello.


I was trying to copy a entire database (with 6 collections) but all my connections are made with secondary preferred read preference. All documents got copied, but all indexes failed to build with this error:

Apparently with primary preferred read preference the same issue occurs. With primary all indexes have been copied.

This should not be considered a problem, it should belong to the normal program error handling.

issuing db.collection.createIndex() on the primary for a replica set

Hello.


Why this should not be considered a problem?


I used the primary preferred read preference too and got the same error. I should be available to ensure indexes with primary preferred read preference, shouldn't I?


If this is a normal execution even so, thank you and got it!
