Failed to find a default file in the app artifacts folder (.next) for Hybrid next.js deployment to Azure Static App from Azure Pipelines

Describe the bug

I am getting the following error when trying to deploy a SSR-supported next.js application to Azure Static App from Azure Pipelines

The structure of the project is very straight forward , the package.json file is on the root folder, the .next folder gets generated under the root folder as well , the folders inside the root look like the image below, please notice that the pages folder sits under /src/pages:

I added a buildAz task, so to create an empty node_modules under the generated .next folder after the build, following the approach detailed on this thread, but the issue seems unrelated:

This is how the azure pipelines looks like:

Expected behavior

Being able to deploy to Azure Static Web apps our existing next.js project without losing the SSR capabilities of next.js as it is now supported https://aka.ms/swa-nextjs-ssr-blog

@camila-akqa Thanks for sharing the logs and package.json.

As you don't want the html export feature of the NextJS, can you please remove the && next export from the build command in your package.json and try again.

Please let me know if it helps. Thanks!

Hi @vivekjilla

Thanks again for looking into this. I am already doing that, so in Az Pipelines I've these field:

app_build_command: 'yarn buildAz'
is_static_export: false
api_location: "" 
output_location: ""

and In the package.json I've defined a task that looks like next:

"buildAz": "cross-env IGNORE_TYPESCRIPT_ERRORS=true next build --no-lint",

Please notice that I tried deploying the same project as static, eg. including "&& next export" in the build command and with the following fields in Azure pipelines , and the site is deployed correctly:

is_static_export: true
api_location: "" 
output_location: "out"

I've made some changes since the last time I posted last message (eg. reducing the size of the node_modules) , so I can reattach the logs if needed.

Really appreciate all help you can provide! thanks.
Camila

Oh @vivekjilla

I actually had this 2 tasks on my package.json

 "build": "yarn generate && cross-env IGNORE_TYPESCRIPT_ERRORS=true next build --no-lint && next export",
    "buildAz": "yarn generate && cross-env IGNORE_TYPESCRIPT_ERRORS=true next build --no-lint",

After your previous comment I anyway changed to be

"build": "cross-env IGNORE_TYPESCRIPT_ERRORS=true next build --no-lint",
    "buildStatic": "yarn generate && cross-env IGNORE_TYPESCRIPT_ERRORS=true next build --no-lint && next export",

And updated the pipeline to use yarn build instead of yarn buildAz, eg:

app_build_command: 'yarn build'

And it is now working!!!!!!!

Thanks a lot for your help!!
