showing error when I capture response data and console log it out using javascript

[YingMasverse]

below is the code and the result is No JSON found in the output

const { exec } = require('child_process');

// Function to run a Bru file and capture the response data
function runBruFile(filePath, callback) {
  exec(`bru run ${filePath}`, (error, stdout, stderr) => {
    if (error) {
      console.error(`Error: ${error.message}`);
      return;
    }
    if (stderr) {
      console.error(`Stderr: ${stderr}`);
      return;
    }
    console.log(`Output: ${stdout}`);
    callback(stdout);
  });
}

// Function to extract JSON from the output
function extractJson(output) {
  const jsonRegex = /\[.*\]/s; // Regular expression to match JSON array
  const jsonMatches = output.match(jsonRegex);
  if (jsonMatches && jsonMatches.length > 0) {
    const jsonString = jsonMatches[0];
    try {
      return JSON.parse(jsonString);
    } catch (parseError) {
      console.error(`Failed to parse JSON: ${parseError.message}`);
    }
  } else {
    console.error('No JSON found in the output');
  }
  return null;
}


runBruFile('Wallet_Service/Public/Wallet/Get_Wallet_List.bru', (response) => {
  // Extract and process the JSON response
  const jsonResponse = extractJson(response);
  if (jsonResponse) {
    const responseData = jsonResponse[0]?.results[0]?.response?.data;
    if (responseData) {
      console.log(`Captured Response Data: ${JSON.stringify(responseData, null, 2)}`);
      // Use the response data as needed
    } else {
      console.error('Response data not found in the JSON output');
    }
  }
});
