# 45109: Skills Limit Exceeded

Log Type: APPLICATION

Log Level: ERROR

## Description

This error occurs when you try to add or save more Skills than the current Flex configuration allows. Flex uses Skills in the Admin UI for skills-based routing, and TaskRouter Worker attributes determine which tasks an agent is eligible to handle.

### Possible causes

* You assigned too many Skills to an agent in Flex Admin or Teams view while updating the agent profile.
* Your application updated a TaskRouter Worker and sent too many values in the `skills` array inside the Worker's `attributes`.
* Your routing design depends on too many individual Skills for the same agent instead of using TaskQueues and TaskRouter expressions to segment work.

### Possible solutions

* Review the affected agent or Worker and remove unused, duplicate, or overly specific entries from the `skills` list before saving again.
* Simplify your routing model by grouping work into broader Skills and then routing with TaskQueues and TaskRouter expressions where appropriate.
* If you manage agents through the API, validate the Worker `attributes` payload before updating the Worker so the `skills` array only includes the minimum set required for routing.
