google-ads-php with version v20.1.0:

• Google Ads API version: V14

Your environment: PHP 7.4

I was checking Upload offline conversion, but I am unable to run this API request due to the below error.
** syntax error, unexpected '|', expecting ';' or '{' in /vendor/googleads/google-ads-php/src/Google/Ads/GoogleAds/Lib/V14/ServiceClientFactoryTrait.php **

I am sharing an example url which I was trying for the offline conversion.
Here is the link:
