+The pipeline run might fail with an error: `failed quota: <quota name> must specify cpu, memory`.
+
+To avoid this error, set a limit range for the namespace, where the defaults from the `LimitRange` object apply to pods created during the build process.
+
+For more information about setting limit ranges, refer to _Restrict resource consumption with limit ranges_ in the _Additional resources_ section.
+====
 
 . After the pods are created, verify the resource quota usage for the pipeline run.
