RangeError [ERR_BUFFER_OUT_OF_BOUNDS]: "length" is outside of buffer bounds in Node.js Pub/Sub

I'm encountering a RangeError [ERR_BUFFER_OUT_OF_BOUNDS]: "length" is outside of buffer bounds error while working with Google Cloud Pub/Sub in a Node.js application. Below is a simplified version of the service I'm using:

@Controller() export class EventController { private subscription; @Get('subscribe') public subscribe(): void { console.log('Subscribing to event'); this.stringSubscriber.subscribe(); console.log('Subscribed to event'); } private stringSubscriber = { subscribe: (): void => { try { this.subscription.on('message', async (message: Message): Promise<void> => { logger.info('[subscribe] [onMessage] message', { message: message.data.toString(), deliveryAttempt: message.deliveryAttempt, }); await this.handleEvent({ message }); }); } catch (error) { logger.error('[subscribe] Error while subscribing', { error }); throw error; } } }; private async handleEvent(event: { message: Message }): Promise<void> { .... } } 

it seems to fail when I send a subscribe request to the pod, however it does print the logs before:

Subscribing to event.

Subscribed to event.
