error messege

Hello good time. I received the API code and the secret code and entered it in the plugin. When I click the authorize button and enter the Gmail profile, in the last step, which should return to the WordPress page and authorize work should be done successfully, I will encounter the following error message. Please advise what is the problem?

Fatal error: Uncaught Error: Call to undefined function Mailster\GuzzleHttp\Psr7\uri_for()
