M365Defender-VulnerabilityManagement - failing deployment every time at Microsoft.Web/sites with ServiceUnavailable error

[SergGu]

Describe the bug
We tried deploying https://github.com/Azure/Azure-Sentinel/tree/master/DataConnectors/M365Defender-VulnerabilityManagement multiple times (using several test subscriptions and several admin accounts) and it fails every time at one of the Function App import stages, the error is seems to be related to storage access.
@anders-alex FYI - you seem to be the last person updating the code.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://github.com/Azure/Azure-Sentinel/tree/master/DataConnectors/M365Defender-VulnerabilityManagement
2. Click on 'Deploy to Azure', provide required customisations (e.g. mandatory lint to Log Analytics)
3. Start deployment
4. See error "Storage access failed. Storage volume is currently in R/O mode. Please delete and recreate backup schedule to mitigate."

Expected behavior
It is expected that deployment will be finished and the Function App will start.

This seems to be a region specific Function App issue. The deployment fails in UK East but works fine in other regions.

Hi @SergGu, Thanks for flagging this issue, we will investigate this issue and get back to you with some updates. Thanks!

@SergGu, Yes, it might be due to the R/O mode switched automatically due to the (backups, update) for that specific time period.
Could you please redeploy it in that region again and let us know if still it has same error.

Ok, Can we close this issue, if its resolve for you?
