@eimantas-gecas-axomic Thanks for raising this issue.
Indeed, this seems to be an oversight as both the original blog post

Don’t forget that you will need to add a Lambda resource policy permission to the function to allow API Gateway to invoke > your function. For example:

aws lambda add-permission
--statement-id dd0dffb7-971e-5952-9699-38493cf34293
--action lambda:InvokeFunction
--function-name "arn:aws:lambda:us-west-1:[your account number]:function:Echo"
--principal apigateway.amazonaws.com
--source-arn "arn:aws:execute-api:us-west-1:[your account number]:[your gateway id]/"

and the relevant Troubleshooting section of the Developer Guide

mention adding a Lambda resource policy permission with the execution_arn value as the source ARN.
I'll address this.

As the AWS documentation states that the REST and HTTP execute-api ARN formats are the same we'll output the execution_arn attribute in the same format as the aws_api_gateway_stage resource's equivalent:

arn:partition:execute-api:region:account-id:api-id/stage

The fix for this has been merged and will release with version 3.3.0 of the Terraform AWS Provider, next week. Thanks to @ewbankkit for the fix. 👍
