I checked online but could not find the solution yet. It would be great if someone can help on this.
Sorry i am not developer but do you mean i need to check if i have this file getallheaders.php?
It seems like in your magento installation - this extension - https://github.com/ralouphie/getallheaders is configured.
Now issue here is this getallheaders extension is require a specific PHP library which is not able to find in your Magento system.
They do have specific installation requirement so if you PHP version is higher then 5.6 you will require to run second command.
If you have PHP version lower then - then you require to run the fist command which mentioned on the same github page. the link above i have given.
That will resolved your issue !
Hope it helps !
