Envoyer deployment of upgraded Laravel 5.6 fails quoting mismatched PHP versions

I've just updated from Laravel 5.2 to 5.6, with all the various composer updated that are required, but my latest Envoyer deployments are failing in the Instal Composer Dependencies stage.

I get the following error message

}

and I have run composer update via terminal on my local machine and the lock file seems to have updated correctly.

I can't see what I'm doing wrong. Can anyone help me out?

Thanks
