API Gateway Lambda GET Method Integration

Terraform Providers AWS
1

I have created an IAC by Terraform for

  • API Gateway
  • Lambda (Java)
  • DynamoDB
  • IAM and Policy

Users can create a POST request to the API gateway and can get data via lambda from dynamodb.

Currently, the method is “POST”.

But when I convert it to “GET”, Then I cannot receive the data.
I have faced the following errors.

{
  "message": "Internal server error"
}


{"x-amzn-ErrorType":["InternalServerErrorException"]}


<AccessDeniedException>
  <Message>Unable to determine service/operation name to be authorized</Message>
</AccessDeniedException>


Lambda invocation failed with status: 403. Lambda request id: ce751387-f7f9-4bb0-9efc-edaa5f5acee7
Execution failed due to configuration error:

Please help someone.
