NullReferenceException reading Excel: 0.0.6-alpha1

[1100594]

When detecting a Excel File from a byte array throws a NullReferenceException at MimeDetective.MimeTypes.FindZipType(ReadResult& readResult) in \src\Mime-Detective\MimeTypes.cs:line 314

var fileData = File.ReadAllBytes(filePath);
var type = fileData.GetFileType();

@clarkis117, this issue only happens on version 0.0.6-alpha1 (pre-release), unfortunately I need some fixes of this version, so I cannot use the previous one.

Additional information: I think that your new "CreateMemoryStreamIfSourceIsNull" method is not working properly resulting in a null Source prop.

@1100594 Thank you for the report will look into this soon 😀

Thank you @clarkis117,

I have more information for you.

The problem is that you trying to change the value of a in "readResult" parameter (aka. readonly ref parameter), please consider remove the "in" keyword or use another approach to change the value of the "source" prop.
