short answer: no. you can’t touch environment variables on n8n Cloud, because it’s a managed service by n8n.

for that error you have two options:

  1. switch to using Binary Data properties for large files
  2. split your data into smaller chunks with the Split In Batches node.

Yeah A_A4 covered it, n8n Cloud is fully managed so you don’t get access to environment variables like `N8N_PAYLOAD_SIZE_MAX`. If you’re hitting payload limits the binary data approach is probably your best bet since it streams the data instead of holding it all in memory, just make sure whatever node is receiving the large file has its “Binary Data” option enabled if it has one. What kind of data are you trying to move around? If it’s like a big API response you might need to rethink the approach vs if it’s file uploads where binary handling is straightforward.
