45109: Skills Limit Exceeded

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.

• 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.

• 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.
