Error while calling dataverse api

Hello everyone,

I have developed an application that saves data on the dataverse. I send a lot of data, but for some of them, I receive an error:

 

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

 

What this errore mean?Can anyone help me?

Thanks.

it's a timeout error, you need to handle how to retry what is failing and/or eventually send the data using a batch request.

@NewDeveloper this a service running a long pool? Can you give more details. Base on what you wrote it looks a connection issue that must handle to avoid that.

Hi, thank you for your response. It’s a service that takes messages from a queue, processes them by inserting the JSON, and calls the Dataverse APIs. I conducted a test by sending 10,000 requests, and about a hundred of them resulted in an error.

@NewDeveloper  so I would recommend read about the API Limitation throughput.

👉 API limits overview (Microsoft Dataverse) - Power Apps | Microsoft Learn

Another item is to instead of using the CreateRequest or UpdateRequest, use the bulk operations for a huge amount of records Use bulk operation messages - Power Apps | Microsoft Learn

 

 If my answer helped you, please give me a Kudo (👍). If solve your question please mark as solution. This is help the community.

I, I had already read about the API limits, so I am trying to be careful. I am not receiving the 429 too many requests error because it is a case that I handle. So, I really can't explain what the problem might be.

there are two other service protection limits other than 429 (too many by one user).

 

  1. combined execution time of all the request by one user.
  2. number of concurrent requests by one user.

is your service a function app or power automate? also, are you updating/inserting records through this service? I'll suggest to distribute your requests to multiple app users, in power automate you could do this by creating a couple of app users and creating and using different connections for individual activities, in code first approaches, you've to create a new ServiceClient connection using a different user.

Hi, thank you for your response. Yes, my code is an Azure Function that writes and updates within the Dataverse. Could you explain better how I can simulate multiple users using the Dataverse APIs? Currently, I request a token and then call the Dataverse APIs directly. How could I simulate multiple users?

Thank you.

You should use ServiceClient class, here you can see in the code snippet, the connection is happening through a clientID and client secret, you can try few things.

 

  1. Implement the ServiceClient as shown below and see if you even need multiple connections/clients.
  2. If you do, then have a couple of clientID/secrets stored in azure key vault and randomly choose one while creating the serviceClient connection. 
  3. If you are implementing some kind of data migration, I'll recommend to use a proper tool e.g. azure data factory, or KingswaySoft SSIS adapter, they internally take care of the paging and service protection error issues.
