We have a system calling n8n (tested and duplicated with Postman). N8N calls a third party system and receives a JSON, cleans the data and SHOULD respond to the calling webhook with that the JSON. We are calling the respond to webhook with all incoming items. N8N says it ran the flow successfully, but our calling system and Postman never get anything back from the n8n respond to webhook. The responding webhook is over 1200 items. Does n8n have a limit that we are reaching with the webhook response?
Edit: I am wrong here, i thought it gave an error if the payload was too big
As long as there isn’t an error then it shouldn’t be, unless something is different on cloud accounts but I doubt it.
Would you be able to share the sample data so i could try it out? I can message you a webhook link where you could send it to if you’re able to share
Plus n8n will save all execution data in the memory, so it may be also a run-out-of-memory issue.
For such a large amount of items better to use an external message broker service (like rabbitMQ or AMQP)
I think I have a cleaned up JSON that has confidential data removed. I tried making a Postman Mock server but it just creashes it.
The JSON is ~2.66Mb currently and ~440,000 lines. Unfortunately I’m limited to getting the data in one call currently so I have to be able to get all of those, and its continuing to grow process and returned to the system. calling and requesting the data. The flow works fine with a smaller data sample.
I got the full data set to run and give me the a json to return, but I doesn’t actually return the data set to the webhhook. Why NOT? It says its done but my postman run that triggered still hasn’t received anything from n8n on the respond to webhook. Postman still says Sending Request. n8n is refusing to send a response back on a larger dataset no matter what I do.
