Steps to Reproduce

import ballerina/http;
import ballerina/io;
import ballerina/time;

final http:Client codeGenClient = check new ("http://localhost:9090", timeout = 350, cache = {enabled: false});

type TestGenRequest record {
    string openapiSpec;
};

type TestGenResponse record {
    string code;
};

public function main() returns error? {

    // string usecase = "Write an http service to read a specified csv file and add it to google sheet.";
    // // string usecase = "Write an application to read open github issues in a given repo and send those as a message to a slack channel.";
    // // string usecase = "Write an application to todos from a csv file and create github issues for each todo.";
    // // string usecase = "Write an application to read all the rows from a nosql db and set those data into another nosql db.";

    TestGenRequest req = {openapiSpec: usecase};
    time:Utc startTime = time:utcNow();
    Resp codeResp = check codeGenClient->/ai/tests.post(req, params= {"temp" : 0, "attempts": 0});
    time:Utc endTime = time:utcNow();
    io:println("Time taken to generate code: ", time:utcDiffSeconds(endTime, startTime));
    check io:fileWriteString("test.bal", codeResp.code, io:OVERWRITE);
}

When you change Resp to TestGenResponse while hovering HTTP client call, you still get an error saying unknown type Resp. which means state is out of sync. you should see the exception in the log.
