How to filter CloudWatch Log Insights with ispresent() function

Question

I'm trying to perform a really simple query on the not so new AWS Cloudwatch Log Insights

I'm following their documentation to filter my logs using ispresent function.

The query is the following:

fields @timestamp, status
| filter ispresent(status) != 0

But this give me an error (the super unhelpful We are having trouble understanding the query)

How can I filter my logs by showing only the logs with the status field?

The accepted answer doesn't work for me, but you can now negate ispresent():

fields @timestamp, status
| filter !ispresent(status)
