# X_BODY_TOO_LARGE

## Means

request body over the transport ceiling

## Typical cause

the request declares or streams more bytes than http.maxRequestBodyBytes, the most this process reads for any route; a signed upload bigger than that cannot be accepted in one request

## Fix

`send it in parts (storage signPart/completeUpload for an upload), or raise the ceiling: configureHttp({ maxRequestBodyBytes: <bytes> }) in the app's http.ts`
