    12.3.5 upgrade error with media picker

    After upgrading to umbraco 12.3.5 this morning I'm getting an error with media pickers in the backoffice not displaying the image. Anyone else having this issue? Upgrade was from umbraco 11.


        "ExceptionMessage": "Method not found: 'System.Threading.Tasks.Task`1<System.String> SixLabors.ImageSharp.Web.RequestAuthorizationUtilities.ComputeHMACAsync(System.String, SixLabors.ImageSharp.Web.CommandHandling)'.",
        "ExceptionType": null,
        "StackTrace": null

    Fixed - I'd installed ImageSharp 3.1.1 instead of 3.0.1

    Yep, had the same issue with an upgrade from v10 and I had used 3.1.0. I rolled back to 3.0.1 and everything seems fine again, thanks.

    I ran into the same issue with version 12.3.3, and upgraded to 12.3.7 and the issue remains. If I try upgrading to 3.1.1 I get the error message

      "Method not found: 'System.Threading.Tasks.Task`1<System.String> SixLabors.ImageSharp.Web.RequestAuthorizationUtilities.ComputeHMACAsync(System.String, SixLabors.ImageSharp.Web.CommandHandling)"

    Any suggestions on this?

    hmmm: Package 'SixLabors.ImageSharp' 3.0.2 has a known high severity vulnerability,

    Is there a way to get this working with 3.1.1? Anyone had any success?

    I think this is relevant

    Especially where it says under v12 ImageSharp 3 cannot be updated due to braking changes (sic)

    I get the feeling you will not be able to use ImageSharp v3 with Umbraco v12

    Presumably you can use ImageSharp v2 (i.e. via install the package Umbraco.Cms.Imaging.ImageSharp2 instead of Umbraco.Cms.Imaging.ImageSharp3)

    Or (probably better) upgrade to Umbraco 13 which is the LTS release while 12 is an STS release.
