Not all batches being processed (HTTP socket gets closed after 4th batch) - Datascope Select REST API

Client is trying to retrieve prices using the following API: #DataScope.Select.Api.Extractions.ExtractionRequests.IntradayPricingExtractionRequest

Because of the number of prices to retrieve it is split up in multiple requests (each time for 1000 instruments).So for each 1000 instruments he does the REST API call and then process them and wait for 30 seconds and do the following call.

In production client saw in the log file that 4 batches are processed OK, but with the fifth batch the HTTP socket was closed. This situation reoccured the next day. Can you please advise what could be the cause?

I checked the log and found the connection has been closed while retrieving a response.

I tested the request message with Postman and Postman can show the response properly.

Does the client has a proxy or firewall server?

The client can share the runnable source code so I can test it in my environment.

@Lukasz Ossowski

Thanks for reaching out to us.

The information is limited so I can't provide the cause of this issue.

You can check those requests in Postman and verify if the fifth batch will be closed. If not, it could be a problem in the application. The client can also share the runnable source code. Then, I can test it in my environment.

Please feel free to reach out if you have any further questions.

Hi Jiraponse,


I tried uploading client's log, but I receive message "something went wrong". Is there any other way to share the file with you?
