Azure Function App - Publish failed

Question

I'm unable to publish (WebDeploy) my Azure Function App (It's a Durable Function, I know it deosn't matter, but, just in case if matters). This started happening today.

I'm getting a "Publish Failed" popup and the below error message in the output window of my Visual Studio.

Error Message

Function Runtime - beta

When I access the Function App Url in a browser I get "Your Function App 2.0 preview is up and running" message". And, I don't see anything wrong in the Kudu portal as well.

I have deleted the Function and re-created it with the same name with no luck.

Any help is much appreciated.

Update : Here is another error that I'm getting as well.

Don't know if this is closed but I had same issue while deploying new SDK version to an older azure function app. Here is what I did: Instead of downloading deployment profile from Azure portal, created a new one with visual studio automated deployment. This is important- While deploying from Visual studio it should ask you to upgrade version of deployed app, click yes and your app will get deployed.

Solution 2

I fixed this issue by setting WEBSITE_RUN_FROM_PACKAGE to 0 on the application settings. I was uploading the function files by syncing a WebDeploy package from Azure DevOps to the App Service file system and not running it from the .zip package.

On https://docs.microsoft.com/bs-cyrl-ba/azure/azure-functions/run-functions-from-deployment-package explains about running Functions from a deployment package and all the benefits of doing it this way, but then remember to:

1. Just upload the .zip deployment package to d:\home\data\sitepackages (don't use the msdeploy verb "sync" to sync the file system at wwwroot)
2. Add a packagename.txt containing only the name of the package file in folder, without any whitespace

Solution 3

Go to azure portal, stop the function app, publish from vs, then start again.

Solution 4

Can't reproduce your error when using WebDeploy with SCM. When I set WEBSITE_WEBDEPLOY_USE_SCM to false(in Application settings) to avoid using SCM, I saw An error was encountered when processing operation 'Create Directory' on 'wwwroot' like the second error you have met.

Several options to try:

1. Visit https://functionappname.scm.azurewebsites.net in browser to check whether your network environment is fine and has no firewall restriction.
2. Check whether you have proxy set like Fiddler when publishing.
3. Go to portal, Reset publish credentials then Download publish profile. Delete old publish profiles and import the new one to publish again.
4. If all of those suggestions fail, delete all old resources relate to the function. Then create a brand new function app with new app service plan and storage. Try to publish to this new app.

Solution 5

This seems to happen to me when I have made changes that for some reason necessitate the following.

1. Rebuild the project (make sure you can run it locally).
2. Click to publish, but prior to that click on "Manage Application Settings" do a quick check and click OK.
3. Attempt to publish.
4. If that fails close visual studio and azure portal (stop running or disable all relevant objects) and repeat.

Worst case create a new profile and deploy to that.

We automated the deployments from VSTS. After looking at your above comment, I tried to publish it again. It's working now. Not sure how it's working now. I didn't make any changes to the Function app.

Repeatly after a few publishs a ran into the same problem and only #4 works. Azure Functions v2 seems not be to ready.

@johnstaveley Have a look at another related problem.

[johnstaveley]

I deployed without zipping and set WEBSITE_WEBDEPLOY_USE_SCM to be an empty string (in Application settings). This worked.

[Mariano Soto]

Worked for me, but after setting WEBSITE_RUN_FROM_PACKAGE I had to delete the publish profile from Visual Studio and add it again
