Object Reference in SyncCommand.ExecuteCommand()

[Gulati-Gaurav]

We are saving our session data in Aerospike. We are getting few errors while retrieving, creating and updating the data with details as followed:

Object reference not set to an instance of an object. 
Stack trace : 
       at Aerospike.Client.SyncCommand.ExecuteCommand() 
       at Aerospike.Client.SyncCommand.Execute() 
       at API.Common.Data.AerospikeDal.ReadRecord()

The error is not very frequent but it occurs once in a while. I have checked every variable I am passing to Aerospike Client but none of them appears to be null.

The error is not reproducible as with the same scenarios, the case gets executed seamlessly when checked again.

What version of the client are you using? You say it happens while retrieving, creating, and updating the data, does that mean it happens during a Put and/or Get operation?

[Gulati-Gaurav]

Aerospike.Client version - 7.0.1
We are getting the error in both put and get operations.

Do you have the full stack trace including line numbers?
Can you share your client policy and read and write policies you are using for these operations?

[Gulati-Gaurav]

I am using Aerospike Nuget Package. Due to this we won't be able to provide the line numbers of the Aerospike Code.

Client Policy :
{
minConnsPerNode = 0,
maxConnsPerNode = 500,
timeout = 1000,
maxSocketIdle = 0,
},

Write Policy:
{
totalTimeout = 1000,
commitLevel = CommitLevel.COMMIT_MASTER,

},

ReadPolicy:
{
readModeAP = ReadModeAP.ALL,
totalTimeout = 1000
},

I have been unable to reproduce the issue. Are you getting any timeout errors? Have you tried any other versions of the C# client?
