Thanks for posting to the Telerik developer forums.
The issue you are reporting consists of a few points which I will address below.
You are correct, the Kendo UI Upload widget does not populate the type
(which corresponds to the MIME type of the file, which most probably for this file types should be application/vnd.ms-outlook
) field of the rawFile
selected when a MSG file is selected. This will be further investigated with the Kendo UI team.
The reason you are getting a 400 status code from the server is not visible from the attached screenshots. Most probably this should be a missing Content-Type header (for example, Content-Type:multipart/form-data;
) and/or a missing field of the file JSON representation. However, to be able to further investigate this issue I would like to ask you to provide a sample that replicates the issue.
I have used the following code
to try to replicate the issue but to no avail. Please use it to provide an example of the issue you encountered (note that you have to enter the API key of your backend project to use the example).
