FileNotFoundException: No files found matching exist in an asset

[hardware]

Hello,

I can't understand the exception bellow when WebOptimizer's tag helper try to access any bundle after a deployment on an Azure App Service. Locally everything works as expected.

Exception details :

There must be something that prevents the taghelper from finding the right file after deployment but I can't figure out what. If I comment the <link rel="stylesheet" href="/css/bundle.css" />, an exception on the JS files is raised as well, if I remove @addTagHelper *, WebOptimizer.Core in _ViewImports.cshtml, I got no exception but obviously the web browser can't find any CSS/JS asset.

Does anyone have an idea?

LigerShark.WebOptimizer.Core 3.0.319 ASP.NET Core 5.0.11

@hardware I have the Same Issue. Have you found a solution?

[benjamin-stern]

For me it seemed that one of the target files had a typo, be mindful of the naming conventions specified in the readme and make sure the file names don't have any typos.

[ezaca]

May this be the same error as mine? I am getting it locally (no docker or anything, just Visual Studio, .Net 5.0 and LigerShark.WebOptimizer.Core 3.0.335 + LigerShark.WebOptimizer.Sass 3.0.58-beta, no incompatibility error on install or build):

pipeline.AddScssBundle(
    GetScssSettings(), // nothing relevant
    "/css/bootstrap.css",
    "/_wwwroot/bootstrap/scss/bootstrap.scss").UseContentRoot();

Bootstrap SCSS files are really in project-folder/_wwwroot/bootstrap/scss/bootstrap.scss. Notice the _, it is on a folder name named differently than wwwroot.

Then I include it as:

<link type="text/css" rel="stylesheet" href="css/bootstrap.css" />

But I get a similar exception stack (most significant parts for brevity)

An unhandled exception occurred while processing the request.
FileNotFoundException: No files found matching exist in an asset

Microsoft.AspNetCore.Razor.Runtime.TagHelpers.TagHelperRunner.RunAsync(TagHelperExecutionContext executionContext)
ElegiaWebsite.App.Pages.Shared.App_Pages_Shared__Layout.<ExecuteAsync>b__17_0() in _Layout.cshtml
...

Am I missing something? I can't find any typo for now. As an extra test, I did set every cache to false, but no luck.

[benjamin-stern]

@ezaca My recommendation would be to only include one library at time and test, for me it one of them had a typo and i found it when including library files iteratively.

I got this issue after updating LigerShark.WebOptimizer.Sass to 3.0.82-beta. I think it must also occur when it can't find a bundle file because after a bit of trial and error I found if I changed pipeline.AddScssBundle("css/site.css", ... to pipeline.AddScssBundle("/css/site.css", ... then it would work again.
