# 19038: Page token must be bigger than or equal to 0

Log Type: APPLICATION

Log Level: ERROR

## Description

This error occurs when you request Chat resources with a `PageToken` value that is less than `0`. `PageToken` must be a non-negative integer when you paginate through results.

### Possible causes

* The request includes a `PageToken` query parameter with a negative value
* Your application decrements the page token below `0` while paginating through Chat messages or other list results
* A client-side validation issue allows an invalid `PageToken` value to be sent to the Chat API
* A variable used to build the request is uninitialized or incorrectly parsed, which results in a negative number

### Possible solutions

* Update your request so `PageToken` is set to `0` or a positive integer
* Add input validation before sending the request to prevent negative `PageToken` values
* Review your pagination logic to make sure previous-page calculations never produce a value below `0`
* If you are storing pagination state, confirm the value is preserved correctly between requests
* Test the request with a known valid `PageToken` value to verify the rest of the request is correct
