Deployment goes through wiithout any errors. Site is live.

Dear Netlify Team,

I have a next.js application running here since quite a while.

Since yesterday night while accessing the Site tthe following message appear:

error decoding lambda response: error decoding lambda response: json: cannot unmarshal number into Go struct field APIGatewayProxyResponse.multiValueHeaders of type string

The last changes were made 7 days ago and back then everything was running smoothly until yesterday night.

Please help. I have no clue what happend here, since I did not change anything.
