EventGridOutput doesn't contain all types for typescript

[kubop]

One way to define connection to an Event Grid is to use identity based connection, see documentation. However, when dealing with Typescript, the connection property doesn't seem to exist:

Argument of type '{ connection: string; }' is not assignable to parameter of type 'EventGridOutputOptions'.

Sample code:

const eventGridOutput = output.eventGrid({    
    connection: 'EmailServiceTopic'
})

Repro steps

1. Create a .ts function
2. Install the latest @azure/functions
3. Define return function output:

import { app, output } from '@azure/functions';

const eventGridOutput = output.eventGrid({    
    connection: 'EmailServiceTopic'
})

app.serviceBusQueue('ACSEmailMessageQueueTrigger', {
    connection: 'ServiceBusEmailQueue',
    queueName: 'emailservice-queue',
    return: eventGridOutput,
    handler: ....
})

Expected behavior

EventGridOutputOptions type should contain connection property.

Actual behavior

Argument of type '{ connection: string; }' is not assignable to parameter of type 'EventGridOutputOptions'.

Known workarounds

Use Javascript instead of Typescript or suppress TS warnings.

Hi @kubop thanks for the report! In addition to the workarounds you listed, you could use output.generic as discussed here
