I\'m receiving the following error with express:
Error: request entity too large
at module.exports (/Users/michaeljames/Documents/Projects/Proj/mean/node
All the helpful answers so far deal with increasing the payload limit. But it might also be the case that the payload is indeed too big but for no good reason. If there's no valid reason for it to be, consider looking into why it's so bloated in the first place.
For example, in our case, an Angular app was greedily sending an entire object in the payload. When one bloated and redundant property was removed, the payload size was reduced by a factor of a 100. This significantly improved performance and resolved the 413 error.
