WP_CLI::error()

Display error message prefixed with “Error: ” and exit script.

Usage

WP_CLI::error( $message, $exit = true )

$message (string|WP_Error|Exception|Throwable) Message to write to STDERR.
$exit (boolean|integer) True defaults to exit(1).
@return (null)

Notes

Error message is written to STDERR. Defaults to halting script execution
with return code 1.

Use WP_CLI::warning() instead when script execution should be permitted
to continue.

When --debug is enabled, this method will also output a backtrace
showing where the error was triggered from, making it easier to identify
problematic code.

# `wp cache flush` considers flush failure to be a fatal error.
if ( false === wp_cache_flush() ) {
    WP_CLI::error( 'The object cache could not be flushed.' );
}
