@threadi Thanks for your reply!

The PHP version that I am currently using is 7.2 version. I do not want to upgrade the current PHP version. Is there any other option that I could try other than updating the PHP version?

Hello @lcf and @jcastaneda

Thank you for your replies!

Here are the error messages that I have.

Do you have any ideas to solve this error?

Thank you in advance!
