408 Request timeout while trying to upload multiple files as separate requests

[knubisoft-hedgehog]

I have web application, that uploads files one by one and I'm encountering an issue while developing locally. If I properly understand, it happens, because of synchronous nature of python, but I would like to know if anybody knows the solution for this issue without incresing number of workers

An example how I upload files in javascript (just for understanding that they are not batched in single request):

filesToUpload.map(async (file) => {
    return await uploadFile(file, onConflict)
})

Right after that on the server side I'm doing:

files = await request.files
file = files.get('file')
uploadToAzure(file)
saveMetadata(file)
...etc

an issue definitely not in azure or any other service
