Symfony 5 — An error occurred while loading the web debug toolbar. #35365

Symfony 5 — An error occurred while loading the web debug toolbar. #35365

Comments

I have set up a new project using «composer create-project symfony/website-skeleton myproject».

The debug toolbar shows the message «An error occurred while loading the web debug toolbar.»

I installed the symfony/apache-pack but the problem is already there.

I searched the web for hours to find a solution and nothing helps.

When I open the javascript console, I have this error : «/myproject/public/_wdt/afab40:1 Failed to load resource: the server responded with a status of 404 (Not Found)»

Is it a bug or a configuration error ?

PHP Programming Error Types

In this post, you will learn about different error types of the PHP programming language.

Programming errors usually stay unobserved till the program is compiled or executed. Errors are the issues or faults that occur in the program, that cause the behaviour of the programme to be unusual, and experienced developers can also cause these issues. A number of the errors inhibit the program from getting compiled or executed. PHP provides a very convenient environment for debugging and error handling.

There are three types of errors in PHP —

PHP Syntax Errors

PHP language has a set of rules called the syntax, which statements must follow to be valid. If a statement does not follow the rules of a language, it is said to be a syntax error. Syntax errors are often called parse errors in a PHP like interpreted language. Syntax errors stop the execution of the script.

 $var = sample'; $x = (3 + 2) * 6); echo ($x); ?> 

In the above code, at the first line, we have missed the opening quotation mark, and the second line of our code is mis-formed as an opening bracket has been omitted.
This script generates the following error message —

Parse error: syntax error, unexpected ''; ' (T_ENCAPSED_AND_WHITESPACE) in parse_error.php on line 2

The parse errors are detected by the parser, which checks the code’s syntax before it is executed.

PHP Runtime Errors

Runtime errors can be harder to detect and fix. Like including a file that does not exist, calling a function that does not exist, failure to check input data, reading or writing to a file that does not exist. These errors stop the execution of the script immediately. This is because PHP cannot proceed without properly executing the statement where the error occurred.

If the required file ‘file.php‘ does not exist, then this generates a runtime error.
This script generates the following error message at runtime —

Fatal error: require(): Failed opening required 'file.php' (include_path='.;C:\php\pear') in runtime_error.php on line 2

PHP Logical Errors

Logical errors can be a harder type of error to find and eliminate. This type of error occurs when perfectly valid code does exactly what it is instructed to do, but that was not what the writer intended. This error does not terminate the execution of the script.

The above snippet of the code is perfectly valid. This compiles and runs successfully without any error messages, but does not do the right thing.

PHP error constants and descriptions

The constants below are always available as part of the PHP core-

1. E_ERROR— A fatal run-time error that cannot be recovered from, such as a memory allocation problem.
2. E_WARNING— A run-time warning. Execution of the script is not halted.
3. E_PARSE— A syntactic error occurred and could not be parsed.
4. E_NOTICE— The script encountered something that could indicate an error. Execution of the script is not halted.
5. E_CORE_ERROR— A fatal runtime error occurred in the engine.
6. E_CORE_WARNING— A nonfatal runtime error occurred during PHP’s initial startup.
7. E_COMPILE_ERROR— A fatal error occurred while compiling the script.
8. E_USER_ERROR— A user-generated error. It is generated in PHP code by using the PHP function trigger_error().
9. E_USER_WARNING— A user-generated warning. It is generated in PHP code by using the PHP function trigger_error().
10. E_USER_NOTICE— A user-generated notice. It is generated in PHP code by using the PHP function trigger_error().
11. E_RECOVERABLE_ERROR— A catchable fatal error.
12. E_DEPRECATED— A run-time notice. Enable this to receive warnings about code that will not work in future versions.
