+title: Err
+description: Applicable to resources returned by the resources.GetRemote function, returns an error message if the HTTP request fails, else nil.

+
+The `Err` method on a resource returned by the [`resources.GetRemote`] function returns an error message if the HTTP request fails, else nil. If you do not handle the error yourself, Hugo will fail the build.
+
+[`resources.GetRemote`]: functions/resources/getremote
+
+In this example we send an HTTP request to a nonexistent domain:
+
+```go-html-template
+{{ $url := "https://broken-example.org/images/a.jpg" }}
+{{ with resources.GetRemote $url }}
+  {{ with .Err }}
+    {{ errorf "%s" . }}
+  {{ else }}
+    <img src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}" alt="">
+  {{ end }}
+{{ else }}
+  {{ errorf "Unable to get remote resource %q" $url }}
+{{ end }}
+```
+
+The code above captures the error from the HTTP request, then fails the build:
+
+```text
+ERROR error calling resources.GetRemote: Get "https://broken-example.org/images/a.jpg": dial tcp: lookup broken-example.org on 127.0.0.53:53: no such host
+```
+
+To log an error as a warning instead of an error:
+
+```go-html-template
+{{ $url := "https://broken-example.org/images/a.jpg" }}
+{{ with resources.GetRemote $url }}
+  {{ with .Err }}
+    {{ warnf "%s" . }}
+  {{ else }}
+    <img src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}" alt="">
+  {{ end }}
+{{ else }}
+  {{ errorf "Unable to get remote resource %q" $url }}
+{{ end }}
+```
+
+{{% note %}}
+An HTTP response with a 404 status code is not an HTTP request error. To handle 404 status codes, code defensively using the nested `with-else-end` construct as shown above.
