Post data from one Netlify function to another

Hi, I am trying to use Netlify functions to POST data from one function to another but I am running into problems. The initial function I call is a background function that runs a Google Page speed audit on several pages - I used a background function because this audit can take several minutes to run. Once this data is collected I want to POST it to another Netlify function that writes it into a Supabase DB.

I have created a reduced test case where i am just trying to send some stringified test data from the background function to the second receiver function, but this doesn’t seem to work - I get no response there at all in the logs.

I know the code is working because if i run it locally in Netlify dev mode it works fine and one function POSTS data to the second no problem, it is only when I deploy that it stops working.

Is there some restriction on sending data between Netlify functions? I asked the AI chatbot and it was useless. It gave me some nonsense about forwarding on the cookies from the first request to the second, but I couldn’t even get a list of the cookies from the request context object to do that.

My receiving function is pretty simple:

export default async (req, context) => {
	// Check if the request method is POST
	if (req.method !== 'POST') {
		return new Response('Method Not Allowed', { status: 405 });
	}

	try {
		// Parse the JSON body from the request
		const body = await req.json();

		// Process the received data
		console.log('Received data:', body);

		// Send a response
		return new Response(JSON.stringify({ message: 'Data received successfully' }), {
			status: 200,
			headers: { 'Content-Type': 'application/json' }
		});
	} catch (error) {
		console.error('Error processing request:', error);
		return new Response(JSON.stringify({ error: 'Error processing request' }), {
			status: 500,
			headers: { 'Content-Type': 'application/json' }
		});
	}
};

Any help would be much appreciated.
Thanks

There’s no limitation as such. You should be able to POST to a different function. Have you tried sending data outside of the Background Function?
