I am currently installing Typescript into a repository with an existing Webpack and Babel setup that includes Styled Components.
Since Babel will take care of compilation, I have configured tsc to perform typechecking only. However, with a simple Typescript React component that defines a Styled Component div, tsc is giving me the following error(s):
core/ui/NoticeBanner/index.tsx:33:6 - error TS2786: 'BannerContainer' cannot be used as a JSX component.
Its return type 'ReactElement<Omit<Omit<Pick<DetailedHTMLProps<HTMLAttributes<HTMLDivElement>, HTMLDivElement>, "key" | keyof HTMLAttributes<...>> & { ...; }, never> & Partial<...>, "theme"> & { ...; }, string | JSXElementConstructor<...>>' is not a valid JSX element.

33 <BannerContainer>
~~~~~~~~~~~~~~~
core/ui/NoticeBanner/index.tsx:41:8 - error TS2786: 'BannerText' cannot be used as a JSX component.
Its return type 'ReactElement<Omit<Omit<Pick<DetailedHTMLProps<HTMLAttributes<HTMLDivElement>, HTMLDivElement>, "key" | keyof HTMLAttributes<...>> & { ...; }, never> & Partial<...>, "theme"> & { ...; }, string | JSXElementConstructor<...>>' is not a valid JSX element.
41 <BannerText>{message}</BannerText>
Here is the component in question:
import React from 'react';
import AlertWarning from 'material-ui/svg-icons/alert/warning';
import ActionInfo from 'material-ui/svg-icons/action/info';
import styled from 'styled-components';
const BannerContainer = styled.div`
background-color: rgba(243, 209, 121, 0.23);
padding: 10px 30px;
margin: 40px 0px;
flex-direction: row;
display: flex;
align-items: center;
`;
const BannerText = styled.div`
margin-left: 13px;
font-size: 18px;
font-weight: 400;
color: #333333 !important;
line-height: 140.28% !important;
`;
interface NoticeBannerProps {
message: string;
status: string;
}
const NoticeBanner = (props: NoticeBannerProps) => {
const { message, status } = props;
return (
<BannerContainer>
<div style={{ display: 'flex' }}>
{status === 'failed' ? (
<AlertWarning className="alert-icon" color="#dc3545" />
) : (
<ActionInfo className="info-icon" color="#8F2C87" />
)}
</div>
<BannerText>{message}</BannerText>
</BannerContainer>
);
};
export default NoticeBanner;

I have tried different versions of Styled Components within v5 as well as different versions of the @types/react and @types/styled-components.
I am a bit stuck on what else I can look into or what I can use to debug the problem.
I am guessing it is either a dependency graph issue (version of @types aren't aligning correctly).
