https://stackoverflow.com/a/39794504' if you aren't using the event system, you will need to disable the feature to suppress the deprecation message, please try changing the value to false like the answer suggests, i hope that helps

Like i am trying to upload a file which is 700MB but i have a MAX_CONTENT_LENGTH of 100MB

Brody•2y ago

try to increase the limit

みなと•2y ago

How The application is working fine in my local machine

Brody•2y ago

are you by chance on the free plan?

みなと•2y ago

Yeah i am

Brody•2y ago

perhaps flask is trying to buffer the 700mb file into memory, but on the free plan you only have 512mb available

みなと•2y ago

Right

You still get 5$ worth of credit every month with the Dev plan 🙂

Hey sorry i just checked in my local machine it is not trying to buffer to RAM there is some CPU usage that is it. What seems to be the problem im not able to debug

Brody•2y ago

You mean excessive CPU usage?

みなと•2y ago

It's just using the CPU for checking the file size if it is below 100MB

Brody•2y ago

There's definitely bigger issues than checking the file size

みなと•2y ago

If we say about uploading im doing that in chuncks of 1024 bytes to the filesystem

Brody•2y ago

Is this example just uploading and saving the file to disk?

みなと•2y ago

Yes that is all it is doing
