command result maximum size is 512 MB

[nadimgeagea95]

I'm using cat - grep combination because i don't want to use sftp to download the whole file as it is too large.
The issue is that that there is a limit on how much a command can return.
I'm writing the result of the command in a file and the size of the file is always 512 MB even though i'm sure that the command returns more than 512 MB.
Is there a way to increase the limit ?

This is my code:

import SSH2Promise = require('ssh2-promise');
const ssh = new SSH2Promise({ uniqueId: id,  ...sshConfig });
const commandResult = await ssh.exec(command);
