Error: A Serverless Function has exceeded the unzipped maximum size of 250 MB. : https://vercel.link/serverless-function-size

[vdatttiwari-complian (Vdatttiwari Compliancean)]

I am trying to deploy my python project with fastapi using vercel, but keep on facing this error: Error: A Serverless Function has exceeded the unzipped maximum size of 250 MB. : Limits.
this is my vercel.json:
{
“builds”: [
{
“src”: “/api/main.py”,
“use”: “@vercel/python”,
“config”: {
“excludeFiles”: “/{.next,.cache,node_modules,public,app}/**"
}
}
],
“routes”: [
{
“src”: "/(.)”,
“dest”: “api/main.py”
}
]

}

this is my build system report.

How can deploy my application without this error

Hi, @vdatttiwari-complian! Welcome to the Vercel Community

It looks like you exceeded the maximum size of 250 MB on your project.

From the documentation:

For Serverless Functions, the maximum uncompressed size is 250 MB including layers which are automatically used depending on runtimes. These limits are enforced by AWS.

You can use includeFiles and excludeFiles to specify items which may affect the function size, however the limits cannot be configured. These configurations are not supported in Next.js, instead use outputFileTracingIncludes.
