      db.createCollection("collation", {collation: {locale: 'en', strength: 2}})
db.collation.insert({a: 'abc'})
db.runCommand({analyze: "collation", key: "a"})
db.runCommand({analyze: "collation", key: "a"})
// MongoServerError: Cannot find index to verify that join fields will be unique

      This error message comes from the $merge stage generated by the analyze command complaining that the collation of the source collection is different than that of the existing statistics collection.
