I have the same issue, but I'm just running npx typewriter init, javascript and node.js as language options.

I got the same when running in dev mode, however if I changed the function below in the generated code

typewriter/src/languages/templates/typescript/analytics-js.hbs

Line 195 in 83b543b

const ajv = new Ajv({ allErrors: true, verbose: true })

from

function validateAgainstSchema(
  message: TrackMessage<Record<string, any>>,
  schema: object
) {
  const ajv = new Ajv({ allErrors: true, verbose: true });

  if (!ajv.validate(schema, message.properties) && ajv.errors) {
    onViolation(message, ajv.errors);
  }
}

to

function validateAgainstSchema(
  message: TrackMessage<Record<string, any>>,
  schema: object
) {
  const ajv = new Ajv({ allErrors: true, verbose: true });
  ajv.addKeyword("labels");

  if (!ajv.validate(schema, message.properties) && ajv.errors) {
    onViolation(message, ajv.errors);
  }
}

Then it works

Thanks for reporting this. The last update came in with the validation that should've been disabled for production. Pushing a fix right now.

The latest release should fix these errors: https://github.com/segmentio/typewriter/releases/tag/v8.0.10

Ping me if this still happens to you!

@oscb still happens to me

1. I upgraded to v8.0.10
2. I removed my generated client and regenerated it
3. I get same issue

here is an example event that's been generated

 export function contactAdded(
    message: TrackMessage<ContactAdded>,
    callback?: Callback
): void {
    const event = withTypewriterContext({
        ...message,
        event: 'Contact Added',
        properties: {
            ...message.properties,
        },
    });
    const schema = {"$id":"Contact Added","$schema":"http://json-schema.org/draft-07/schema#","description":"Player adds a contact","labels":{"area":"account","type":"contacts"},"properties":{"id":{"$id":"/properties/id","description":"the user contact id","type":"string"},"type":{"$id":"/properties/type","description":"The type of contact (MOBILE,EMAIL,ADDRESS)","enum":["ADDRESS","EMAIL","MOBILE"],"type":"string"}},"type":"object"};
    validateAgainstSchema(event, schema);

    const a = analytics()
    if (a) {
        a.track(event,callback);
    } else {
        throw missingAnalyticsNodeError
    }
}

and the validateAgainstSchema function

function validateAgainstSchema(
    message: TrackMessage<Record<string, any>>,
    schema: object
) {
    const ajv = new Ajv({ allErrors: true, verbose: true })

    if (!ajv.validate(schema, message.properties) && ajv.errors) {
        onViolation(message, ajv.errors)
    }
}

The error is

Error: strict mode: unknown keyword: "labels"
