Function app backup failed username or password incorrect

[Pablitox07]

Hello guys. I'm running into this issue where the custom backups of my function app fail. The error says that the username or password are incorrect, but when you configure the custom backup in the function app you never enter a password, you just select the storage account and the container where you want to store the backups. Not sure why I'm getting this error.

Do you guys know something that I can troubleshoot about this error?

Hello @PesalaPavan
Sorry I forgot about the documentation I used. I used the following documentation to create the custom backups https://learn.microsoft.com/en-us/azure/app-service/manage-backup?tabs=portal#configure-custom-scheduled-backups
Is it configured to create a custom backup everyday.

@PesalaPavan thanks. Could this issue be related to managed identity or something like that?

Pablitox07 , From my sample test following the doc, I'm not seeing this error/issue.
Is this issue confined only to this Function app or shows the same behavior on other apps as well?

If you haven't tried this already so, navigate to Azure Portal > Open the Function app on the Azure portal, run Diagnose and solve problems : Configuration and Management and Availability and performance options to fetch more details about the error.

Azure Functions currently supports two versions of the runtime host. The following table details the currently supported runtime versions, their support level, and when they should be used:
Upgrade or migrate to supported version as required: Recommended runtime version for functions in all languages.

Hello. Actually no. I'm very stuck with this issue, mostly because there is almost no documentation about this error
