Invalid value for <appServicePlanResourceGroup>, it only all

Error message

Invalid value for <appServicePlanResourceGroup>, it only allow alphanumeric characters, periods, underscores, hyphens and parenthesis and cannot end in a period.

What it means

Raised by AzureFunctionsDeployCommand.validateParameters when the resource group configured for the App Service plan fails its pattern check (illegal characters or a trailing period). This is a separate setting from the function app's own resource group; like it, the App Service plan resource group must contain only alphanumerics, periods, underscores, hyphens and parenthesis and cannot end in a period, and validation aborts the deploy before any Azure client is initialized.

Solutions

1. Fix the App Service plan resource group name to use only permitted characters
2. Remove any trailing period from the value
3. Confirm the setting in the azure-functions plugin configuration (appServicePlanResourceGroup) matches an actual Azure resource group
