For my portfolio I am calling data from my API related to specific projects of mine whose pages are dynamically generated with Next.js. Anyway, I make the call to the API but am missing deeper information that I can’t seem to extract.

export const getServerSideProps = async (context) => {
	const pid = context.query.pid;
	const url = process.env.STRAPI_API_URL;

	const query = qs.stringify(
		{
			populate: '*',
		},
		{
			encodeValuesOnly: true,
		}
	);
	const res = await axios.get(`${url}/projects/${pid}?${query}`);

	const projectData = res.data.data;

	return { props: { projectData, url } };
};

This returns:

‘samples’ is fully populated but ‘technologies’, which is a relational content type, is missing an ‘icon’ field (which is a media type) that I cannot seem to populate.

I’ve tried every request configuration listed here but nothing seems to work.

Maybe someone has an idea? Even a separate query like ‘http://localhost:1337/api/projects/1?populate[technologies][fields][0]=icon’ returns a 500 error.

Hi there, you’ll need to populate at each level of query, here is an example I was using that populates multiple levels etc.
