Logging can be a life-saver when it comes to discovering bugs or faults in your Go (Golang) code. The three most popular ways to log errors in Golang are: This article will walk you through how to log errors using each method, when and why you’d want to use each, along with examples.
The Python KeyError is an exception that occurs when an attempt is made to access an item in a dictionary that does not exist. The key used to access the item is not found in the dictionary, which leads to the KeyError.
The Python SyntaxError occurs when the interpreter encounters invalid syntax in code. When Python code is executed, the interpreter parses it to convert it into bytecode. If the interpreter finds any invalid syntax during the parsing stage, a SyntaxError is thrown.
The Python ImportError: cannot import name error occurs when an imported class is not accessible or is in a circular dependency.
A MemoryError means that the interpreter has run out of memory to allocate to your Python program. This may be due to an issue in the setup of the Python environment or it may be a concern with the code itself loading too much data at the same time.
The JavaScript error TypeError: null is not an object occurs when a property is accessed or a method is called on a null value. This specific error message is shown only on Safari. Other browsers display a different message for this error. Error message: Error Type.
The TypeError: Cannot read property 'length' of undefined is one of the most common type errors in JavaScript. It occurs when the length property is read on an undefined variable. Error message: Error Type.
A ServiceConfigurationError is thrown in Java when a service provider cannot be loaded successfully. For instance, the format of the provider-configuration file appears to violate some aspect of the specification.
A FormatFlagsConversionMismatchException is an unchecked runtime exception which is thrown when a conversion and a flag are incompatible in the source code. This is a very common exception encountered when the programmer tries to format the string. Unless otherwise specified, passing a null argument to any method or constructor in this class will cause a NullPointerException to be thrown.
The NoCredentialsError is an error encountered when using the Boto3 library to interface with Amazon Web Services (AWS). Specifically, this error is encountered when your AWS credentials are missing, invalid, or cannot be located by your Python script. These credentials are stored by default at ~/.aws/credentials which contains your access key and secret access key for using AWS services, along with other configuration details such as your region code.
