You must specify a subscription id to use for deployment as

Error message

You must specify a subscription id to use for deployment as you have more than one

What it means

Raised by AzureFunctionsDeployCommand.getTargetSubscriptionId when no default subscription id is configured and the account has more than one selected subscription, so the deployment target is ambiguous. The helper auto-selects when exactly one subscription is available; with several it refuses to pick one arbitrarily and requires an explicit choice.

Solutions

1. Specify the subscription id explicitly via the azure-functions plugin configuration (subscriptionId parameter)
2. Reduce the selected subscriptions in the Azure account to a single one
