Hi @ankitdhanna,

Thanks for sharing this—it sounds like you’re receiving a 500 error occasionally, is that right?

If so, how often are you seeing this? Are you seeing a delay in the response from the API, or is it taking a long time? Please provide as much additional detail as possible.

Thank you!
Will
