blockchain project

I am having issues with my project, when ever i try to access create wallet i get this error 'Undefined constant "Tatum\Sdk\Psr7\Http\CURL_HTTP_VERSION_2_0", i will attach screenshot, please check if you can fix it before you bid on this project thanks, the dapp was built on laravel, you should also have good knowledge of vps, because the website was hosted with vps.
