Is there a size limit for listeners?

Hi ​@Kevin Mok,

We are also working on a plugin which is triggered using webhooks. We are trying to test it with a dummy payload from postman.

We are getting 500 Internal Server Errors once we exceed around 0.6 MB (significantly less than 1MB). We are not sure if the error is because of the payload size or something else. But we are not getting errors in smaller payloads. Also, there are no logs in Moveworks to troubleshoot this and the cutoff is not clear, same payload works sometimes and gives error at other times when it is near this size.

Can you help identify the issue for us? Is it size issue or is it something else?

Here is an example screenshot:

Worked fine with payload size ~ 0.5 MB. (See content length highlighted)

Got error with 0.57 MB:

​@vinitb can you DM me your listener name and org you are testing this in?

DM’ed you.

Hey ​@vinitb  and ​@Joel.Matias - Quick correction, I got back from the engineering team and after doing some testing, we still do have that 1MB cap. But the problem is that the cap includes both the parsed_body and the raw_body(the string version). So, the limit is going to be around ~500kb instead. Sorry about the confusion, I am updating our doc site as we speak

Hi Kevin,

Thanks for the update!

Any chance the limit can be increased? We are hitting this limit when trying to send notifications to a few hundred users. But we expect to send notifications to at least a few thousand users if not more.

We will have to batch the webhooks payload into smaller chunks for now, but it would be great if we didn’t have to do that.

​@vinitb - I passed your feedback along to the team, I can’t guarantee anything in the short term. For now, a batching approach as you mentioned would be the best solution!
