02/21/2025, 3:41 PMHi Vapi Team... We need some urgent help here. Our calls started failing with HTTP 413 errors, which we had not encountered before.
This error indicates that the request entity is too large, and our initial assessment suggests that this may be due to recent changes in the payload sizes or server configurations.
Our call is being dropped
Details:
Issue: HTTP 413 (Payload Too Large) errors
Observation: Errors have begun occurring recently;
Please let me know if you need further details or access to relevant logs.

"id": "93c229d0-8c81-43b5-ac99-d070517d2ba2",
@Leo do you have any specific call ID or complete error response?
l
Leo
02/21/2025, 4:42 PMNo, because we are not able to create some calls using the CreateCall API
Leo
02/21/2025, 4:43 PMDoes the TwilioCallSid helps?

Leo
02/21/2025, 4:45 PMJust sent
Leo
02/21/2025, 4:47 PMAre there any change related to the max payload size that we should be aware of? (I didn't find anything in the changelogs or in the API doc)
s
Shubham Bajaj
02/21/2025, 4:49 PMNo there are not any changes.
Shubham Bajaj
02/21/2025, 5:09 PM@Leo @merrells Switch to using POST /call endpoint instead of /call/phone and check your request body size - it may be too large.
l
Leo
02/21/2025, 5:13 PMYes, the error we start receiving today indicate that, what is the max size? This started today (we're actively monitoring any issues when we manifest an assistant, and we haven't had this issue before)
Leo
02/21/2025, 5:15 PMAre there any infrastructure/cloudflare changes related to the payload size?
s
Shubham Bajaj
02/21/2025, 5:17 PM@Leo No new changes have been pushed, keep your request body size under 100KB
l
Leo
02/21/2025, 5:25 PM@Shubham Bajaj I think there is an issue in Vapi. The payload we sent that Vapi rejects does not have 100KB
Copy code
Content-Length 97303Leo
02/21/2025, 5:25 PMWe capture another ones that have less than 80KB

02/21/2025, 5:34 PMWe are having the same problem since today, a payload problem but we are getting the 413 error.

02/21/2025, 5:34 PMsomething surely has changed.

02/21/2025, 5:34 PM@Shubham Bajaj bump here, this is affecting our side as well

02/21/2025, 5:35 PMGoing here might help as well to get some attention

Damiano Rodriguez
02/21/2025, 5:36 PMMaybe you didn't change anything but something has changed maybe under the hood for some of your provider. We are getting a cloudflare error from your side.

02/21/2025, 5:37 PM@Damiano Rodriguez @Nomadiction @Leo Looking into it.
l
Leo
02/21/2025, 5:38 PMSame here Damiano. Maybe it's a new cloudflare rule
n
Nomadiction
02/21/2025, 5:48 PMI did a quick test, and the limit seems to be exactly 63.98KB
Nomadiction
02/21/2025, 5:48 PMOne extra char and I get the error
Nomadiction
02/21/2025, 5:49 PMProbably 64KB with the headers
