[TharmiganK]

Description:

Adding @openapi:ServiceInfo{embed: true} annotation to a service fails with Method too Large error

Steps to reproduce:

Run the following sample code :

import ballerina/openapi;
import ballerina/http;

# Represents location
public type Location record {|
   # Name of the location
   string name;
   # Unique identification of the location
   string id;
   # Address of the location
   string address;
|};

# Represents a collection of locations
public type Locations record {|
   # collection of locations
   Location[] locations;
|};

# Represents the unexpected error
public type SnowpeakError record {|
   # Error message
   string msg;
|};

# The response for the unexpected error
public type SnowpeakInternalError record {|
    *http:InternalServerError;
    # The payload for the unexpected error
    SnowpeakError body;
|};

@openapi:ServiceInfo {
   embed: true
}
service /snowpeak on new http:Listener(9090) {

    # Snowpeak locations resource
    # 
    # + return - `Location` or `SnowpeakError` representation
   resource function get locations() returns Locations|SnowpeakInternalError {
       return {body: {msg: "Internal Server Error"}};
   }
}
