How to fetch all the coinbase pro transactions correctly in php

I have a question of coinbase pro,

How can I get all the orders/transactions from coinbase pro using php without any limit , or with any limit parameter.

I am using the following library to fetch all the coinbase pro orders , but it only gives me 100 orders from the below method.

fetch_orders

Here is the method,

$CoinbaseProtrans = $CoinbasePro->fetch_orders('ETH/USD',"",150,array('limit'=>100,'after'=>1));
echo "<pre>";print_r($CoinbaseProtrans);echo "</pre>";

Here is the error I am getting,

Fatal error: Uncaught ccxt\ExchangeError: coinbasepro after cursor value is not valid in coinbasepro.php:813 

Here is the link of the library:
