PDF is not loading on mac

[Maral]

Hi,

I'm running a project based on razor pages that uses pdfviewer page and page model. I am running on the mac environment and I use VS community 8.2.5.

I am using the following OnPOSTLoad() for my 

public IActionResult OnPostLoad([FromBody] Dictionary<string, string> jsonObject)

        {

            if (jsonObject == null)

            {

                return this.Content($"{nameof(jsonObject)} is null");

            }

            try

            {

                if (jsonObject.TryGetValue("document", out var fileName))

                {

                    var documentPath = GetDocumentPath(fileName);

                    if (!string.IsNullOrEmpty(documentPath))

                    {

                        var pdfRenderer = new PdfRenderer();

                        var jsonResult = pdfRenderer.Load(documentPath, jsonObject);

                        return Content(JsonConvert.SerializeObject(jsonResult));

                    }

                    else

                    {

                        return this.Content(jsonObject["document"] + " is not found");

                    }

                }

                else

                {

                    return this.Content($"document is missing in {nameof(jsonObject)}");

                }

            }

            catch (Exception ex)

            {

                return this.Content($"Exception: {ex}");

            }

an exception occurs on line

 var jsonResult = pdfRenderer.Load(documentPath, jsonObject);

following is the exception info:

Message : Object reference not set to an instance of an object.

Source : Microsoft.Extensions.Caching.Abstractions

StackTrace:    at Microsoft.Extensions.Caching.Memory.CacheExtensions.TryGetValue[TItem](IMemoryCache cache, Object key, TItem& value)\n   at Syncfusion.EJ2.PdfViewer.PdfRenderer.Load(String filePath, Dictionary`2 jsonObject)\n   at AHC.BaseTemplate.Areas.CommandCenter.Pages.CareGapManager.GuidelinesModel.OnPostLoad(Dictionary`2 jsonObject) in /Users/mamir/mygit/CC-vNext/AHC.WebApps/Areas/CommandCenter/Pages/CareGapManager/Guidelines.cshtml.cs:line 122

So I have not been able to load the pdf document. I have to mention that this problem does apply when running the code in the windows env and the pdf document loads in windows.

I very much appreciate any help.

Thanks,

Maral

*Update:

After you mentioned the changes applied to version 17.2.0.39, I downgraded my asp.net core package to 17.2.0.34 and now it is working! Thank you so much for your help. I really do appreciate it.

Kind Regards,

Maral
