Unsuccessful to create ad_group_ad

[Segev Solomon]

Hi,
Im using Make.com to (Google Ads Campaign Management
* application) to create an API request to create an ad_group_ad.*I created 
a shared_bedget, campagin and ad_group before i tried to create an 
ad_group_ad.
this is the API call I did:
    { "type": "list", "fields": { "status": "ENABLED", "ad.name": "test - 
15177eaa-5791-4224-a534-405f659990f9", "ad_group": 
"customers/8385664870/adGroups/163623219253", "ad.final_urls": 
"https://www.example.com/";, "ad.display_url": "https://example.com";, 
"ad.responsive_display_ad.headlines": "responsive display ad HEADLINE ", 
"ad.responsive_display_ad.descriptions": "responsive display ad 
descriptions", "ad.responsive_display_ad.business_name": "business name", 
"ad.responsive_display_ad.long_headline": "responsive display ad long 
headline", "ad.responsive_display_ad.marketing_images": 
"https://promoter.co.il/content/images/5809f581-ee43-4430-b297-cab7725465c1.png";,
 
"ad.responsive_display_ad.control_spec.enable_autogen_video": false }, 
"_version": "v16", "clientId": "83XXXXX870", "resource": "ad_group_ad" }

and this is the error I got:
