How to configure CorsRule for CDK using python

I am trying to figure out the proper syntax for setting up cors on an s3 bucket using CDK (python). The class aws_s3.CorsRule requires 3 params (allowed_methods, allowed_origins, max_age=None). I am trying to specify the allowed_methods which takes in a list of methods but the bases is enum.Enum. So how do I create a list of these methods. This is what I have tried but it doesn't pass validation.

s3.Bucket(self, "StaticSiteBucket",
        bucket_name="replaceMeWithBucketName",
        versioned=True,
        removal_policy=core.RemovalPolicy.DESTROY,
        website_index_document="index.html",
        cors=s3.CorsRule(allowed_methods=[s3.HttpMethods.DELETE],allowed_origins=["*"],max_age=3000)
        )

The only thing Im focused on is the cors line:

cors=s3.CorsRule(allowed_methods=[s3.HttpMethods.DELETE],allowed_origins=["*"],max_age=3000)

Trying to read the documentation is like peeling an onion.

https://docs.aws.amazon.com/cdk/api/latest/python/aws_cdk.aws_s3/HttpMethods.html#aws_cdk.aws_s3.HttpMethods

I tried calling each one individually as you can see using s3.HttpMethods.DELETE but that fails when it tries to synthesize.

looks like you at least forgot to wrap the param you pass to cors as a list. I agree that the docs are a bit of a rabbit hole, but you can see the Bucket docs specifies the cors param as (Optional[List[CorsRule]])

This is mine:

from aws_cdk import core
from aws_cdk import aws_s3
from aws_cdk import aws_apigateway

aws_s3.Bucket(self,
    'my_bucket',
    bucket_name='my_bucket',
    removal_policy=core.RemovalPolicy.DESTROY,
    cors=[aws_s3.CorsRule(
        allowed_headers=["*"],
        allowed_methods=[aws_s3.HttpMethods.PUT],
        allowed_origins=["*"])
    ])

So yours should be:

cors=[s3.CorsRule(
    allowed_methods=[s3.HttpMethods.DELETE],
    allowed_origins=["*"],
    max_age=3000)]
