This issue is resolved. AWS must have changed their rules on the XSS validation because their WAF was the cause of the problem. I added an exclusion for odata within our XSS rules and now it's working fine. Thanks for the info on the intervals changes. We will update that as well.

well crap...that didn't actually fix it. It stopped the files from creating new versions every time, but it's still getting a 403 when we use the word "style" anywhere.

Still interested in finding out why it's saving the file every 15 seconds. I will continue looking in to the style issue

I have tracked down the issue. In our S3 configuration, we use Versioning. This is is causing 2 issues. The first is that it's creating a new version every 15 seconds in our S3 bucket. The other is, it's stopping anything with a Style tag to be able to be saved for some reason. I am not sure what Style has to do with anything, but as soon as I suspended versioning in our S3 bucket, everything saves perfectly now.

Why would it keep saving a version of a non-changing file every 15 seconds? This has turned our < 2MB file store in to a 90+GB file store since it's been running so long.

Freeze Edits isn't on for sure. I double checked that. Also, it allows me to save just fine when no Style is involved.

We don't use a proxy, but we are saving to S3 for our stuff. Is it possible that something within the S3 saving could be causing this? Is there a way to debug/troubleshoot/log where this might be coming from?

I am not sure what in the work would cause this, but if i add a template and put inline style or a style tag in it, i get a 403. If i change nothing except that style tag it works fine. I don't even know what would cause a 403 in the first place. There don't seem to be any logs for 403. The PATCH call to https://**************/odata/templates(cdGdbjDSZP5JBfPh) is the same except the Request Payload. The 2 different payloads are below. I have tried it on your playground and it doesn't seem to error. I am using 2.11.0.

Any ideas?

Works fine:

    "recipe": "html",

FAILS:

Ok. It seems to work fine in Firefox, so it must just be something Chrome/Edge does differently. I don't like it, but it doesn't seem like there is anything you guys can do about it. Thanks

First, i apologize if this was already asked and answered, but i didn't see it when searching.

I am testing using your standard playground report https://playground.jsreport.net/w/admin/hBfqC7af

I am using Chrome (and I also tried in Edge). When i click Save from the embedded viewer, my only save option is html.

If I use my server (since your's doesn't allow for download after it's rendered) and forcibly save it as PDF, it won't open because it says it's corrupt.

Is there a way to generate a real PDF file and not an HTML file?

Thanks!

This is definitely an issue with the Simple OData Client.

You can see in their source that they are trying to use Enum.Parse which will not take the data annotations in to account
https://github.com/simple-odata-client/Simple.OData.Client/blob/5d2cc4d93fdb98a93e3966d10d1ae5b038017831/src/Simple.OData.Client.Core/Extensions/DictionaryExtensions.cs

I worked around it using

    public class TempTemplate : jsreport.Types.Template
    {
        string tmpRecipe;

        [System.Runtime.Serialization.DataMember(Name = "folder")]
        public Folder Folder { get; set; }

        public new string Recipe
        {
            get {
                return tmpRecipe;
            }
            set
            {
                tmpRecipe = value;
                base.Recipe = JsonConvert.DeserializeObject<Recipe>($"\"{value}\"");
            }
        }
    }

Here is the stacktrace for the error as well

I get random serialization issues. I am not sure if it's an issue with JS Reports though. I think it may be an issue with the Simple OData client or maybe the JSReports .NET Types project.

If i run this code in C#, i get an error of "Object of type 'System.String' cannot be converted to type 'System.Nullable`1[jsreport.Types.Recipe]'."

var test1 = await client.For<Template>()
                        .Filter($"name eq '{Request.Form["renderFormat"]}' and ({string.Join(" or ", folderList.Select(l => "folder/shortid eq '" + l + "'").ToArray())})")
                        .FindEntryAsync();

This code generates the following OData query (which is correct)

This sends the request and gets back the following response from JSReports:

{

      "folder": {
        "shortid": "gKhiKDU"
      }
    }
  ]
}

Just to test that it's not the query or OData, i ran the following C# code and it produced the correct dictionary of values

var test = await client.For("template")
                        .Filter($"name eq '{Request.Form["renderFormat"]}' and ({string.Join(" or ", folderList.Select(l => "folder/shortid eq '" + l + "'").ToArray())})")
                        .FindEntryAsync();

If I use a template with a recipe of "html" this error doesn't happen. I have already had to create my own class to be able to handle Folder/ShortId while waiting for your next update, do you think this can be resolved by overriding Recipe? Here is what I have had to do to create my own class that i use for other templates (I created a reusable fodler and i know most of those DataMember attributes don't need to be there...i was testing)

    public class Folder
    {
        [System.Runtime.Serialization.DataMember(Name = "shortid")]
        public string Shortid { get; set; }

        [System.Runtime.Serialization.DataMember(Name = "name")]
        public string Name { get; set; }

        [System.Runtime.Serialization.DataMember(Name = "folder")]
        public Folder ParentFolder { get; set; }
    }

    public class TempTemplate : jsreport.Types.Template
    {

        [System.Runtime.Serialization.DataMember(Name = "folder")]
        public Folder Folder { get; set; }
    }
