Image source is missing error

[pke]

My styled Image component gets its source from the theme context like this:

export const BackgroundImage = styled(CrossfadeImage).attrs(props => ({
  source: imageSource(props.theme.cover),
  resizeMode: "cover",
  blurRadius: 50,
}))`
  position: absolute;
  left: 0;
  right: 0;
  bottom: 0;
  top: 0;
  z-index: -1;
  justify-content: flex-start;
  align-items: center;
  flex: 1;
`;

However the TS compiler is complaining about a missing source prop when using the component like this <BackgroundImage/>
Is there a way to tell the TS compiler that this component does not need a source prop, in fact MUST NOT allow a source prop?
