Azure Function Deployment is failing

Question

I'm deploying to the Azure Function via yaml pipeline and VS Publish profile, but it's failing the deployment with below non-understandable error.

##[debug]getDeploymentLogs. Data: {"statusCode":200,"statusMessage":"OK","headers":{"content-length":"147","connection":"close","content-type":"application/json; charset=utf-8","date":"Fri, 11 Aug 2023 11:25:43 GMT","server":"Microsoft-IIS/10.0","cache-control":"no-cache","expires":"-1","pragma":"no-cache","x-ms-request-id":"<id>","x-aspnet-version":"4.0.30319","x-powered-by":"ASP.NET"},"body":[{"log_time":"2023-08-11T11:25:38.0464127Z","id":"<id>","message":"Fetching changes.","type":0,"details_url":null}]}

Background - Previously it was working, but I have added ARM deployment for Function App Settings.

        "name": "[concat(parameters('<function-name>'), '/', 'appsettings')]",
        "type": "Microsoft.Web/sites/config",
        "apiVersion": "2022-09-01",
        "dependsOn": [ 
            "[resourceId('Microsoft.Web/sites', parameters('<function-name>'))]"
        ],
        "tags": {
            "displayName": "azwenprd01-devtst-pos-if1101-2-func-AppConfig"
        },

But it failed as I used dependsOn for Function App which I'm not deploying through ARM. I removed dependOn and then ARM template got deployed. After this step I have added FunctionDeployment in my yaml pipeline. But after that, Function deployment were failing which was working previously.

Also, I checked all the files on Kudu. I observed that the ZIP is getting deployed under '\data\SitePackages>' but not getting extracted to wwwroot folder. Also the packagename.txt conatians the older .zip name.

Not sure what's causing this issue. Can we do the clean redeploy to Azure Function ? Or how to forcefully deploy to Azure Function ?

WEBSITE_RUN_FROM_PACKAGE is set to 1.

Answer 1

i had a case where the access token had expired and the deploy failed in the way shown above. getting an actual and valid token set up cured it. (these error message is probably not that intuitive and also not that clearly leading to the root cause.)

You can refer my SO thread answer with the ARM code to deploy Function app.
