Lambda@Edge for "origin request" doesn't receive custom headers

0

I have a CloudFront distribution with S3 origins. In the origin settings there are custom headers added (i.e. "x-test"). The behaviour has two Lambdas: for "origin request" and "origin response" hooks (both NodeJS). It is all completely fine with the one for "origin response" hook, but the one for "origin request" doesn't receive "x-test" header in the event...headers object. All the docs and articles I've read say that "origin request" Lambda should get this header too. Tried to add "x-test" header to whitelist in attached "origin request policy" - this didn't help. Cannot find ANY information why could this happen. Does anyone have any ideas?

    Can you share from which object are you trying to read the custom header from?

    Sure. event.Records[0].cf.request.headers The same works perfectly for the function for "origin response"

I have finally found them. For "origin request" hook they are here: event.Records[0].cf.request.origin.s3.customHeaders and if origin is ALB: event.Records[0].cf.request.origin.custom.customHeaders
