Hi, I am Magento1 certified developer with "Developer Plus" certification having 7.5+years of working experience in web development, along with almost 1.5+year of working experience in web development, majorly in custom development, theme implementation and migration. I have checked your requirement and screenshot provided. But screenshot does not revile much information, we need to check your logs, but just wondering is this error coming for other payment method too? Also which magento version is in use ? Lets discuss further at your convenience. Thanks
