Serverless framework fail to deploy due to s3 method - error reason: FUNCTION_ERROR_INIT_FAILURE

Question

I am having a method in my app (NodeJS deployed as lambda in AWS using Serverless framework), that I use to get the list of items in an S3 bucket.

Method:

const getObjectsList = async (bucketName, path) => {
    let s3 = new AWS.S3();
    let prefix = `${path}/`;
    let params = {
        Bucket: bucketName,
        Prefix: prefix,
    }

    let result = await s3.listObjectsV2(params).promise();     //CAUSE OF THE FAILURE

    return result.Contents ?? [];
}

The issue it that I am getting the following error log when I try to deploy the service having that method:

UPDATE_FAILED: AppProvConcLambdaAlias (AWS::Lambda::Alias)
Provisioned Concurrency configuration failed to be applied. Reason: FUNCTION_ERROR_INIT_FAILURE

But the service gets deployed successfully without any issue if I comment let result = await s3.listObjectsV2(params).promise(); so I came to the conclusion that the failing cause is that method, but why is that? Am I missing something? I would like to also note that the app runs without any issue locally.

Serverless Config File (IAM part)

provider:

        Resource:

          - arn:aws:s3:::{HERE_COMES_THE_NAME_OF_MY_BUCKET}/*
