handleUpload is not being called from .on method to handle /upload request

[VALERYRAMIREZ]

Hi, how are you?, and thanks for this example.

I'm trying to apply your method to upload a file to the esp32 (in my case the content is JSON) but even tough the request is being done correctly to the esp32 then after receiving the request then the equivalent handleUpload in my code is not being called, I say this because none of the messages that I have in my implementation of handleUpload as you defined it here are displayed, I made this post in stackoverflow where I tell the problem.

I think all the arguments of handleUpload are automatically generated and passed to it by the .on method but I'm no sure. Can you help me with this?.

Thanks in advance ofr the help
