• Description of the issue: When searching for documents in an application written in c# via API, they get an error since May 13th 2025: the response casts an exception - The server is experiencing problems.  Please try again later.
  
  This url works in swagger but stopped working yesterday:

  https://svenskamassan.ungerboeck.net/PROD/api/v1/Documents/10?search=Type%20eq%20'C'%20AND%20Subject%20eq%20'INV'%20AND%20EnteredOn%20gt%20DateTime'2025-05-07'%20%20AND%20substringof('Faktura%20-%20Basware'%2C%20Description)%20AND%20substringof('FAKT'%2C%20EnteredBy)

• Account name: Svenska Mässan
• Region: EMEA
• Client version: 25.1

• Steps to reproduce:
  The issue cannot be reproduced in API Help.
  If they use it from SDK, there is an error.

  
  string downloadedDocumentAsBASE64 = EBMSApiClient.Endpoints.Documents.Download(orgCode, document.Type, document.SequenceNumber ?? 0, optionsDoc);

• Observed results vs Expected results: The client gets an error in SDK, but it should work fine just like in API Help
• What is the job the client is trying to accomplish:
  Searching for documents using an app written in C# via API
• Business impact if not resolved:
  Usually they can create over 100 invoices in a day, now their flow for invoices sent to customers is halted.

  Hi all!
  
  I'm thinking there's a bit of confusion surrounding this.  Download Document and Document Search return different things.
  
  - Document /Download - This returns the byte array representing the document file
  - Search Document - This is the search where you return document information stored in Enterprise.
  
  The document.download() functionality in the SDK should be working, at least to some degree.  We've got 4 unit tests implementing it successfully every night.
  
  Here's a snippet of functionality that is succeeding:
  
        const string orgCode = "10";
       const string type = "9";
       const int sequenceNumber = 14178;
  return apiClient.Endpoints.Documents.Download( orgCode, type, sequenceNumber);
  
  In the code example, I am not a fan of it passing in 0 as a fallback parameter.  Not much point to that and would be a 404 at best, error at worst.
  
  The search URL parameter looks valid.  I ran it myself:
  
  Type eq 'C' AND Subject eq 'INV' AND EnteredOn gt DateTime'2025-05-07'  AND substringof('Faktura - Basware', Description) AND substringof('FAKT', EnteredBy)
