Azure-pipelines-tasks: Azure Function deploy fails with The user name or password is incorrect

[federicoD]

Environment

I'm using VSTS

• Account name: stamp-dev
• Release name: Stamp BigBro
• Release number: BigBro-Dev-30
• Agent: Hosted Agent (2.129.1)

Issue Description

I use Azure Service App Deploy to deploy an Azure Function to my Azure environment, and I keep on getting an error saying that username & password are incorrect.

If I delete the Azure Function and I create it again, the deployment works the first one/two times, than I get the same error.

I'm having the exact same problem. Tried Reset publish credentials, but that didn't help either.
I downloaded the publishing profile and used the credentials in there to ftp to the resource location, without any luck. So I'm guessing there is indeed something wrong with the credentials.

[markbeij]

Download app content doesn't work either:

The user name or password is incorrect.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.IO.IOException: The user name or password is incorrect.

@federicoD , @markbeij , Can you please share the app names in private?

Also, share the MSDeploy command from the logs with log time. (mask only the app name)

[pmatwiejuk]

Same here, and what's more - I can't even access Kudu:

I think that problem is connected somehow with the "Slots", as before enabling that I didn't have any problems like that.

[vincent1173]

@pmatwiejuk , Please share the app name in private.

This error usually happens if you delete or regenerate the keys for the storage account associated with the function app. The one defined in the WEBSITE_CONTENTAZUREFILECONNECTIONSTRING App Settings for the functionapp.

If you deleted that storage account, you can try recreating it and updating the app settings that point to it. Check for WEBSITE_CONTENTAZUREFILECONNECTIONSTRING, AzureWebJobsDashboard, AzureWebJobsStorage

If you just regenerated the keys for that account, then update the connection strings in the App Settings for your app.

[federicoD]

@ahmelsayed I've a task to add variables to the AppSettings, but the task removes all the variables so I'm missing WEBSITE_CONTENTAZUREFILECONNECTIONSTRING. Do you think that could be the problem?

[federicoD]

So my problem was due to the fact that the task for replacing the variables was deleting WEBSITE_CONTENTSHARE and WEBSITE_CONTENTAZUREFILECONNECTIONSTRING. So the first time VSTS was able to deploy because the variables where there, the task to set the variables was executed after...so the second time it was failing because of the missing variables.

[vincent1173]

@federicoD , You can also use Azure App Service Deploy task to update the App Settings / configuration settings. This might reduce the complexity of other task that removes the old value.

To resolve the current issue, you can refer to this thread.

Proposed answer from above thread:

[markbeij]

Same problem here, I'm using Apply variables to Azure webapp from Pascal Naber (Xpirit)
There is a checkbox 'Overwrite existing configuration' which you should carefully consider

[vincent1173]

@markbeij , is the issue resolved once you regenerated the keys?

[markbeij]

Yes

[vincent1173]

Closing the issue, as the issue is resolved.
You can update the App Settings / Config settings using App Service Deploy task.

[zorkind]

I just want to say that the CONTENT_SHARE and the other connectionstring setting is ONLY for CONSUMPTION plans!

As stated in this article:
https://docs.microsoft.com/en-us/azure/azure-functions/functions-app-settings#azurewebjobsstorage

If you apply this settings on a diff plan, your App will stop working.

I have been having the same issues here today. After reading the above and the troubleshooting issues document I know what I have done wrong, but it would be nice if the error handling on publish provided a meaningful error and also the Azure Portal could do some validation to stop you from removing required configuration settings. I normally created Azure Functions using my Web App resources, but today ran out of available resources so made one under the consumption plan. I copied my configuration from an existing Azure Function, which caused the issue.
