No debugger available, can not send ‘variables’

by

When you encounter an error message stating “no debugger available, cannot send ‘variables'”, it typically means that you are trying to debug your code without access to a debugger tool or the necessary environment variables are not set up correctly.

Here’s an explanation of the issue and a possible solution:

1. What does “no debugger available, cannot send ‘variables'” mean?

Debuggers are tools that help developers analyze and debug their code by allowing them to set breakpoints, inspect variables, and step through the code execution. However, in some cases, the debugger might not be available or properly configured.

The error message “no debugger available, cannot send ‘variables'” indicates that the current environment or setup does not support a debugger or is unable to send variable information for debugging purposes.

2. Possible causes and solutions:

2.1 Lack of debugger tools:

If you do not have a debugger tool installed or available for your particular development environment, you may encounter this error. In this case, you can consider installing or enabling a debugger tool to help you debug your code effectively.

2.2 Improperly configured debugger:

If you have a debugger tool installed but it is not properly configured, you may encounter issues where it cannot send variable information. Make sure your debugger is set up correctly and compatible with your code and development environment. Check the debugger’s documentation for instructions on configuration.

2.3 Missing environment variables:

Another possible cause is the absence of necessary environment variables that the debugger requires to function properly. Ensure that the relevant environment variables are set up correctly and are accessible to the debugger.

3. Example:

Let’s say you are using JavaScript and encountering the error message “no debugger available, cannot send ‘variables'” in your browser’s console when trying to debug a code snippet:

// Example JavaScript code
  function calculateSum(a, b) {
    return a + b;
  }
  
  const result = calculateSum(5, 10);
  console.log(result);
  debugger; // The debugger statement triggers a breakpoint for debugging

In this example, if there is no debugger tool available or properly configured in your browser, you might see the mentioned error message. To resolve it, you can:

  • Install a debugger extension or add-on to your browser, such as the Chrome DevTools or Firefox Developer Tools.
  • Ensure that the debugger tool is working and correctly connected to your code.
  • If necessary, set up any required environment variables or configurations to enable proper debugging.

By following the appropriate steps based on your specific development environment and programming language, you should be able to overcome the “no debugger available, cannot send ‘variables'” error and effectively debug your code.
