Fix a short .NET #C code - Error 415

I am looking for a skilled .NET C# developer to fix a short code that is currently throwing an "Error 415: Invalid Content Type". I have the full source code available for the project, so the developer will have access to all the necessary files and resources (We are trying to connect with [login to view URL] API. We can provide credentials on an account for this). The main requirement for this project is to resolve the specific error message by addressing the invalid content type issue. The fix needs to be implemented within 24 hours, as there is a sense of urgency to resolve this problem. using (HttpClient httpClient = new HttpClient()) { string endpointUrl = "https://api.ecommerceapi.uk/v1/products"; var data = new { Title = "Test", Description = "Test Description" }; string jsonData = [login to view URL](data); var content = new StringContent(jsonData, [login to view URL], "application/json"); HttpRequestMessage request = new HttpRequestMessage([login to view URL], endpointUrl); [login to view URL] = content; [login to view URL](new [login to view URL]("application/json")); [login to view URL] = new AuthenticationHeaderValue("Basic", [login to view URL]([login to view URL]("key:secret"))); HttpResponseMessage response = await [login to view URL](request); } Ideal Skills and Experience: - Proficiency in .NET C# programming language - Strong understanding of HTTP status codes, specifically Error 415: Invalid Content Type - Experience in troubleshooting and debugging code - Familiarity with handling media types and content types in web applications If you have the necessary skills and can complete the fix within the specified timeline, please submit your proposal.
