Hello Angelica!
Sorry to hear this is happening. 429s are a rate limit error. It sounds like something with the chat is hitting an endpoint to often or making to many requests in a single moment. I have put our documentation below:
https://developer.genesys.cloud/platform/api/rate-limits
https://developer.genesys.cloud/organization/organization/limits#outbound
The best route would be to open a ticket with support and have them look into what is happening, like you have already done.
I hope your issue gets resolved soon!
