Create a new PikeError.
Human-readable error message
Optionalcause:
Error
The underlying error that caused this error
Optional Readonlycause
The underlying error that caused this error (if any). Overrides Error.cause from the base Error class.
Readonlylayer
The layer where this error occurred.
Optionalstack
Staticstack
The Error.stackTraceLimit property specifies the number of stack
frames collected by a stack trace (whether generated by
new Error().stack or Error.captureStackTrace(obj)).
The default value is 10 but may be set to any valid JavaScript
number. Changes will affect any stack trace captured after the value has
been changed.
If set to a non-number value, or set to a negative number, stack traces will not capture any frames.
Get the full error chain as a readable string.
Get all errors in the chain as an array.
Returns a string representation of an object.
Staticcapture
Creates a .stack property on targetObject, which
when accessed returns a string representing the location in the code at
which Error.captureStackTrace() was called.
const myObject = {};
Error.captureStackTrace(myObject);
myObject.stack; // Similar to `new Error().stack`
The first line of the trace will be prefixed with
${myObject.name}: ${myObject.message}.
The optional constructorOpt argument accepts a function. If
given, all frames above constructorOpt, including
constructorOpt, will be omitted from the generated stack trace.
The constructorOpt argument is useful for hiding implementation
details of error generation from the user. For instance:
function a() {
b();
}
function b() {
c();
}
function c() {
// Create an error without stack trace to avoid calculating the stack trace twice.
const { stackTraceLimit } = Error;
Error.stackTraceLimit = 0;
const error = new Error();
Error.stackTraceLimit = stackTraceLimit;
// Capture the stack trace above function b
Error.captureStackTrace(error, b); // Neither function c, nor b is included in the stack trace
throw error;
}
a();
OptionalconstructorOpt:
Function
Staticprepare
Error that originates from the Pike subprocess.
Pike errors typically involve:
