Problem Statement/Rationale
I'm facing issue with projection query syntax after migrating to atlas, I have upgraded mongodb driver from version 3 to 5, when i try running project query in atlas, I'm facing this error :
Failed to retrieve documents[lk_uat.ivrTreeConfig@Uat atlas [replica set: atlas-6mtsco-shard-0]] Database error!Stacktrace: |_/ java.lang.Exception: [lk_uat.ivrTreeConfig@Uat atlas [replica set: atlas-6mtsco-shard-0]] Database error! |____/ Mongo Server error (MongoQueryException): Query failed with error code 31250 with name 'Location31250' and error message 'Path collision at solutions' on server lk-mongo-uat-01-shard-00-02.y3cij.mongodb.net:27017
Steps to Reproduce
Table contents :
*
{ "_id" : ObjectId("5ea87643ce371e745912e21c"), "name" : "A", "description" : "Description...", "text" : [ \{ "name" : "A_1", "text" : "Content1" },
{
"name" : "A_2",
"text" : "Content2"
}
],
"solutions" : [
{
"text" : "1",
"action" : "A"
},
{
"text" : "2",
"action" : "B"
},
{
"text" : "",
"action" : "A"
},
{
"text" : "12",
"action" : "C"
},
{
"text" : "11",
"action" : "D"
}
]
}*
Query when version 3 of mongoDB
db.getCollection("ivrTreeConfig").find({ "name" : "A", "$and" : [{ "solutions" : { "$elemMatch" : { "text" : "2" } } }] }, { "solutions.$" : 1, "solutions" : 1,"action" : 1 });
Expected Results
{
"_id" : ObjectId("5ea87643ce371e745912e21c"),
"solutions" : [
{
"text" : "2",
"action" : "B"
}
]
}
Actual Results
Failed to retrieve documents[lk_uat.ivrTreeConfig@Uat atlas [replica set: atlas-6mtsco-shard-0]] Database error!Stacktrace: |_/ java.lang.Exception: [lk_uat.ivrTreeConfig@Uat atlas [replica set: atlas-6mtsco-shard-0]] Database error! |____/ Mongo Server error (MongoQueryException): Query failed with error code 31250 with name 'Location31250' and error message 'Path collision at solutions' on server lk-mongo-uat-01-shard-00-02.y3cij.mongodb.net:27017
Additional Notes
But I can achieve the same result after mongoDB version upgrade with this query
db.getCollection("ivrTreeConfig").find({ "name" : "A", "$and" : [{ "solutions" : { "$elemMatch" : { "text" : "2" } } }] }, { "_id": 1, "solutions.$": 1});
Can i know why the projection query is not working in the the newer version or atlas, If you could provide me documentation of the same
