We were using MongoDb in our project and Hangfire was working perfectly fine over there but after we have shifted to CosmosDb Hangfire has stopped working, we are using MongoClient only to connect to CosmosDB by passing CosmosDB connection string to MongoClient everything is fine with this MongoClient object but Hangfire is not working with this. It is creating Hangfire default collections into the CosmosDB and when we are trying to manually execute any of the jobs from Hangfire dashboard it gives us this error:
fail: Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[1] An unhandled exception has occurred while executing the request. MongoDB.Driver.MongoBulkWriteException`1[MongoDB.Bson.BsonDocument]: A bulk write operation resulted in one or more errors. WriteErrors: [ { Category : "DuplicateKey", Code : 11000, Message : "E11000 duplicate key error collection: bomHangfire2.core.hangfire.jobGraph. Failed _id or unique index constraint." } ]. at MongoDB.Driver.MongoCollectionImpl`1.BulkWrite(IClientSessionHandle session, IEnumerable`1 requests, BulkWriteOptions options, CancellationToken cancellationToken) at MongoDB.Driver.MongoCollectionImpl`1.<>c__DisplayClass30_0.

hangfire has a cosmos db example:

2023-09-07T19:53:45.6233333+00:00 looks like you opened an issue on the GitHub site.
your only other option if you don't have support from hangfire, would be to clone the project, build the library and use it instead of the nuget package. then debug. once you have a fix, do a pull request.
I don't use hang fire, but a quick look at the code shows it uses jobid for _id. in mongo db this field must also be unique. so somehow in your implementation it generating duplicate jobids.

Sorry for the delay in my response.
Can you try our vCore architecture and let us know if you see the same issue?

2023-09-20T05:52:27.81+00:00 @Oury Ba-MSFT Sorry, but didn't tried vCore architecture as it looks like it is related to database but right now we are not changing our database and if I am wrong you can correct me.
