An error occurred (UnauthorizedOperation) when calling the DescribeVpcEndpoints operation: You are not authorized to perform this operation

Question

I am getting this error while executing my lambda

An error occurred (UnauthorizedOperation) when calling the DescribeVpcEndpoints operation: You are not authorized to perform this operation.

My Policy details :

I have attached above policy to Lambda execution role.

I would suggest that you simply modify your statement to;

            {
              "Sid": "IngestionClusterNodes",
              "Effect": "Allow",
              "Action": [
                "s3:*",
                "glue:*",
                "kms:*",
                "sns:*",
                "cloudformation:DeleteStack",
                "cloudformation:DescribeStackResource",
                "cloudformation:DescribeStackResources",
                "cloudformation:DescribeStacks",
                "cloudformation:ListStackResources",
                "cloudwatch:*",
                "elasticmapreduce:*",
                "secretsmanager:GetSecretValue",
                "secretsmanager:CreateSecret",
                "secretsmanager:PutResourcePolicy",
                "secretsmanager:UpdateSecret",
                "iam:GetGroup",
                "ec2:*",
                "events:*",
                "logs:*",
                "ses:*",
                "sns:*",
                "sns:Publish"
              ],
              "Resource": ["*"]
            }

Just a note, VPCendpoint don't have Arns. Only id, vpce-092e602ea1a16886e so your ec2:* in resource block didn't allow you to describe vpc endpoints.
