"The specified key does not exist" for VueJS app deployed on deployed on S3 with CloudFront

Question

I have deployed a VueJS app with S3 and CloudFront using Route53. It seemed like everything was working fine. I'm able to visit the site at https://my-domain.com, and I can navigate to different routes that I have set up with Vue router. However, when I try to access https://my-domain.com/about directly, I see the following error:

This XML file does not appear to have any style information associated with it. The document tree is shown below.
<Error>
<link type="text/css" id="dark-mode" rel="stylesheet" href=""/>
<style type="text/css" id="dark-mode-custom-style"/>
<Code>NoSuchKey</Code>
<Message>The specified key does not exist.</Message>
<Key>about</Key>

</HostId>
</Error>

Here are the settings for my AWS resources:

All properties are disabled (I don't have static website hosting set since I'm using https)

        }
    ]
}

CORS configuration

Nothing is set here

Route53

I have a domain that has a hosted zone with 5 records:

• mydomain.com: A Record; Points to CloudFront distribution

• Default NS and SOA records that I have not changed

• *.mydomain.com: A record; Also point to CloudFront distribution for frontend subdomains

• api.mydomain.com: A record; Points to an ALB for backend API service

I don't have any origin groups set up. I'm not sure if I need this but it sounds like it could help solve this issue.

I have also heard of AWS Amplify (https://console.aws.amazon.com/amplify/).

What settings can I change so that I can have non-root requests to my domain be routed to the VueJS app?

Answer 1

I got this issue fixed by simply adding index.html in error document section in your s3 bucket -> edit static website hosting -> error document

Answer 2

This is a typical issue with SPAs, because those routes like /dashboard are not real physical routes on the server. To fix this, just open your CloudFront distribution, go to the "Error Pages" tab, and create a Custom Error Response with the following settings:

This is essentially telling CloudFront to ignore a 404 error and just return an HTTP 200 response, and point to /index.html. Your SPA will handle any "page not found" errors internally via Vue Router. This might help with that.
