Describe the Issue

We publish our API documentation based on our Postman collection. In addition to adding new folders and requests, we often move existing folders and requests to improve readability. Because of the difficulty of identifying changes, the most convenient method to update has been to use Replace a collection's data and let Postman sort out the merge.

When the file size approaches 10 to 12 MB, Postman often returns the error: "Request body size limit exceeded," or the gateway returns 504 Gateway Timeout errors.

Steps To Reproduce

1. Create a collection of 10 to 12 MB.
2. Download the collection.
3. Submit the collection using Replace a collection's data
4. Receive an error.
