Error when executing command with streaming stdout/stderr callbacks

Sample code

ssh.connect(sshOptions).then(function() {

            Utils.formatLogs(hostname, "SSH comamnd : " + commandToExecute)


            ssh.exec(commandToExecute, {
                onStdout(chunk: any) {
                    console.log('stdoutChunk', chunk.toString('utf8'));
                },
                onStderr(chunk: any) {
                    console.log('stderrChunk', chunk.toString('utf8'));
                    throw chunk.toString('utf8');
                }
            });
        });

Error

TypeError: a.forEach is not a function
at shellescape (E:\GithubNew<user>\node_modules\shell-escape\shell-escape.js:7:5)

Start with the ssh.exec call shown in the issue and trace how its command arguments reach shell-escape, including the reported node_modules/shell-escape/shell-escape.js failure. Reproduce the streaming stdout/stderr callback example and determine the expected argument shape; done means the example executes without the TypeError.
