Deployment time HTTP ERROR 500

Deployment time getting HTTP ERROR 500
This is not the first time I am deploying. scriptcase version 9.7.013

Permissions for Folders: 755 and for Files 644 – already given.
it is asking for a first-time password (scriptcase as usual). once the password is passed, this error is coming.

it reaches up to :

and HTTP ERROR 500


OK, get it done for this time.
The production server was PHP v 8.x
Once I downgrade to PHP 7.3, then worked.

What is the max PHP supported by 9.7.013?


PHP 7.3. That is the point many users here are anxious for Scriptcase with PHP 8.1.
