What will be the cause this DXA Error for MediaItem class?

Question

Please help me out for this issue. Is this the cause of contentUrl?

Caused by: com.sdl.webapp.common.impl.mapping.SemanticAnnotationException: The field private java.lang.String com.sdl.webapp.common.api.model.entity.MediaItem.url has a @SemanticProperty annotation with prefix 's', but the entity class has no @SemanticEntity annotation with this prefix.

This is the available in MediaItem class in Common API jar.

@SemanticProperty("s:contentUrl")
@JsonProperty("Url")
private String url;
