Puppeteer in AWS Lambda: Error Target Closed or Timeout

Question

I have an application that updates GitHub usernames via API and an attribute that is only accessible via UI.

The flow of the application is as follows:

user submits form > write to sheet > trigger: filter sheet & POST to lambda > lambda event: update usernames and attribute > return update confirmation to sheet

When I run the application I get one of two errors

1. INFO TimeoutError: Navigation timeout of 30000 ms exceeded
2. Protocol error (Target.createTarget): Target closed

I've passed the following args to the browser from what I've seen in other discussions.

['--no-sandbox', '--use-gl=egl', '--single-process', '--headless']

Additionally, I had to set the browser context to incognito to get around authentication and redirects.

When I ran the application the first time, it successfully updated the username and the attribute for each user. When I rerun the application the usernames are change but receive either INFO TimeoutError: Navigation timeout of 30000 ms exceeded or Protocol error (Target.createTarget): Target closed for updating the attribute.

```
# Lambda logs success on first run
INFO    Promise { [ { status: 'fulfilled', value: [Object] } ] }
