502 cannot unmarshal number into Go struct field APIGatewayProxyResponse.multiValueHeaders

Dear Netlify Team,

i have a react next.js application running.
Since yesterday night I get this message:

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

The last changes from my side were 7 days ago and back then everything worked until yesterday night.

Please help. The system is live.

hey there,

We posted a fix on this thread, and I am going to close this one to keep everything in one place :+1:
