Every time we try to update our agent in Retell, we receive an error saying, “item in conversation flow version exceeds size limit. Please reduce the size of the data” that prevents us from making the update. The agent ID is agent_462783cf7fac60ccaebd8901f6

Hi @sean1

Thank you for providing this information. I’ve escalated it to our team for further review.

In the meantime have to tried to reduce the size.

We’ll keep you updated as soon as we have more information.

Best regards

Hello @sean1 We have just tested it, and it appears to be working, but the agent is very large and is about to reach the maximum storage size limit for a single conversation flow. This is a hard infrastructure constraint that cannot be changed.

To resolve this, you’ll need to reduce the overall size of your conversation flow. Here are some approaches:

  1. Split into multiple agents/flows — Break your flow into smaller, more focused conversation flows and use call transfers between agents to connect them.
  2. Trim unused nodes and edges — Remove any nodes, edges, or transitions that are no longer needed.
  3. Shorten prompts — Condense lengthy node prompts where possible.
  4. Reduce dynamic variables — Remove any dynamic variables that aren’t actively used.

Thank You
