Create a Next.js application for Builder 2. Deploy it with SST (which deploys it to AWS) 3. Try to create a page and preview it via Builder Notice that on step 3, you’ll get the following error: ![image](https://us1.discourse-cdn.com/flex020/uploads/builder/original/2X/5/5794c4a9e3afb4adfadc6c69a570886e3b654740.png) The link that the preview is trying to hit is [https://pages.vrio.dev/b0975e23e2414930ae315bf23821fc88/p/ecommerce-page-test?builder.space=b0975e23e2414930ae315bf23821fc88&builder.cachebust=true&builder.preview=ecommerce-page&builder.noCache=true&\_\_builder\_editing\_\_=true&builder.overrides.ecommerce-page=1d407db63efe457fbe2e7e1fe86ce202&builder.overrides.1d407db63efe457fbe2e7e1fe86ce202=1d407db63efe457fbe2e7e1fe86ce202&builder.overrides.ecommerce-page:/b0975e23e2414930ae315bf23821fc88/p/ecommerce-page-test=1d407db63efe457fbe2e7e1fe86ce202](https://pages.vrio.dev/b0975e23e2414930ae315bf23821fc88/p/ecommerce-page-test?builder.space=b0975e23e2414930ae315bf23821fc88&builder.cachebust=true&builder.preview=ecommerce-page&builder.noCache=true& __builder_editing__ =true&builder.overrides.ecommerce-page=1d407db63efe457fbe2e7e1fe86ce202&builder.overrides.1d407db63efe457fbe2e7e1fe86ce202=1d407db63efe457fbe2e7e1fe86ce202&builder.overrides.ecommerce-page:/b0975e23e2414930ae315bf23821fc88/p/ecommerce-page-test=1d407db63efe457fbe2e7e1fe86ce202). If you take the last query string parameter and URL encode it, you get the following link: [https://pages.vrio.dev/b0975e23e2414930ae315bf23821fc88/p/ecommerce-page-test?builder.space=b0975e23e2414930ae315bf23821fc88&builder.cachebust=true&builder.preview=ecommerce-page&builder.noCache=true&\_\_builder\_editing\_\_=true&builder.overrides.ecommerce-page=1d407db63efe457fbe2e7e1fe86ce202&builder.overrides.1d407db63efe457fbe2e7e1fe86ce202=1d407db63efe457fbe2e7e1fe86ce202&builder.overrides.ecommerce-page%3A%2Fb0975e23e2414930ae315bf23821fc88%2Fp%2Fecommerce-page-test%3D1d407db63efe457fbe2e7e1fe86ce202](https://pages.vrio.dev/b0975e23e2414930ae315bf23821fc88/p/ecommerce-page-test?builder.space=b0975e23e2414930ae315bf23821fc88&builder.cachebust=true&builder.preview=ecommerce-page&builder.noCache=true& __builder_editing__ =true&builder.overrides.ecommerce-page=1d407db63efe457fbe2e7e1fe86ce202&builder.overrides.1d407db63efe457fbe2e7e1fe86ce202=1d407db63efe457fbe2e7e1fe86ce202&builder.overrides.ecommerce-page%3A%2Fb0975e23e2414930ae315bf23821fc88%2Fp%2Fecommerce-page-test%3D1d407db63efe457fbe2e7e1fe86ce202) That link works. So the issue is that AWS Cloudfront can’t handle the `:` in the query string. In my opinion, this query string should be URL encoded _to start_ never mind that it’s breaking my specific application. **Code stack you are integrating Builder with** Next.js, SST, & AWS. ---

Hi @manish-sharma , Has there been any update on this? I am also running into the same issue with deploying using SST. This is the query that CloudFront is blocking, “:” characters are not allowed in query parameters. ![image](https://us1.discourse-cdn.com/flex020/uploads/builder/original/2X/7/70bf57ae5ff15c22cbf2f29f72723f68115e3d40.png) ![image](https://us1.discourse-cdn.com/flex020/uploads/builder/original/2X/c/c6c3612827761f17df8116d506df53bb44a32c85.png) I have been unable to find a way to configure AWS to ignore this problem. The only workaround I have found is to edit the query in the iframe of the visual builder, allowing me to live edit and publish changes. However, this is not optimal as I have to do this every time I load the page. ![image](https://us1.discourse-cdn.com/flex020/uploads/builder/original/2X/c/c40b9a70433837906bb1eeb35fe1a3cfa3693fe9.png)
