However SERVER-49990 removes `setSlaveOk` which users are used to and the MongoError still alludes to.
rs0 [direct: secondary]> db.getMongo().setSlaveOk(true)
|
MongoshDeprecatedError: [COMMON-10003] setSlaveOk is deprecated.
|
Trying to set slaveOk does not point users to anything relevant. If you discover the alias (SERVER-49990) and try this the error is a little more helpful at least:
rs0 [direct: secondary]> db.getMongo().setSecondaryOk(true)
|
MongoshDeprecatedError: [COMMON-10003] Setting secondaryOk is deprecated, use setReadPref instead
|
Making the setSlaveOk and setSecondaryOk errors the same would at least make this a little easier for users to action. Adding documentation links to the errors would be even better
