Deploying a Function App from Azure Devops results in Offset to Central Directory cannot be held in an Int64.

Repro steps.

We have an Azure DevOps CICD pipeline that deploys a function app to an elastic windows app service plan with 10 instances. From time to time, we get this error message : Offset to Central Directory cannot be held in an Int64. Bellow are the details of the error log as obtained from azure.

The log/error given by the failure.

Debug your Azure website remotely.

App name: func-acq…ite-qa-01 We can provide more details if needed.

Mention any other details that might be useful.

Seems like a random error that happens often when the approval on the deployment stage is performed hours after the build was initially kicked.

Azure Devops Task Details: `

          - task: AzureFunctionApp@1
            displayName: 'Deploy function app'
            inputs:
              appType: functionApp
              appName: $(tfOut.function_name)
              azureSubscription: ${{ variables.subscription }}
              package:  ${{ variables.artifactPath }}
              deploymentMethod: runFromPackage

`

Tried also using deploymentMethod auto and runFromZip but nothing changed.

The generated package size does not exceed 20mb.
