Spring boot with MongodB but connection to Azure Cosmos - mongodb

Question

I am having spring Mongodb app, I wanted to take it to Azure. So, I decided to use Cosmos db. I made following changes to my application.properties file
spring.data.mongodb.uri = mongodb://[username]:[password]#[dbname].documents.azure.com:10255/?ssl=true
spring.data.mongodb.database=dbname
I am getting following exception:

Answer 1

This error - “Too many 'included' paths (106) specified in policy. A maximum of 100 is allowed.” - occurs when you create created multiple indexes on the account and exceed the limit (100). However, you don’t have to create most of these indexes (if any) as, in contrast to MongoDB, CosmosDB automatically indexes all paths in the document, explicit indexes aren’t required. Try to exclude createIndex/ensureIndex commands and their Spring equivalents unless they have to do with creating unique indexes (you need createIndex for that as we don’t know which fields you want this constraint on).
