OmniPay SagePay服务器方法 - RedirectionURL 5006错误

Question

为了给你一些背景知识，我写了一个使用Omnipay包装PaypalExpress和SagePayDirect的支付类。它工作正常，但是，我还需要添加SagePayServer。不幸的是，经过三天的工作，我无法让SagePayServer正常工作。我一直得到＆＃34; RedirectionURL 5006＆＃34;错误，这只是一个包罗万象的错误。 SagePay绝对是我的网址，但由于某种原因，付款失败，它给出了这个错误。

SagePay和OmniPay都有糟糕的文档和缺乏良好的工作示例，所以感谢任何帮助。

这是我的代码的核心（需要进行大量调整才能使Stack Overflow更简单）：
