There is no feature with name

Error message

There is no feature with name: {name}

What it means

Thrown by FeatureManager.Get when GetOrNull(name) returns null — i.e., no Feature with that name is registered in the feature definition dictionary. Unlike the TryGet-style API, Get is the strict accessor and throws AbpException for unknown names.

Solutions

1. Fix the feature name string to match the registered definition exactly.
2. Register the feature in a FeatureProvider added to Configuration.Features.Providers.
3. Use GetOrNull or IsEnabled instead of Get when absence is an expected case.
4. Migrate persisted feature settings that reference renamed/removed features.

Example fix

// before
var feature = featureManager.Get("ExportData"); // not registered

// after
var feature = featureManager.GetOrNull("MyApp.ExportData");
if (feature == null) { /* handle missing definition */ }

var feature = featureManager.GetOrNull(name);
if (feature == null)
{
    Logger.Warn($"Unknown feature: {name}");
    return false;
}

bool FeatureExists(FeatureManager fm, string name) => fm.GetOrNull(name) != null;

try { return featureManager.Get(name); }
catch (AbpException ex) when (ex.Message.StartsWith("There is no feature with name"))
{
    Logger.Warn($"Feature not registered: {name}");
    return null;
}

When it happens

Trigger: Calling FeatureManager.Get("SomeFeature") (directly or via feature value APIs that resolve definitions) with a name never registered by any FeatureProvider, or after the provider defining it was removed.

Common situations: Typo in feature name string; feature defined in a module not loaded in this environment; renaming a feature in code while old persisted feature values/settings still reference the old name; tests missing module registration.
