Error : x-fb-cd-contents : ['contents'] must be an array."

[baptiste74]

I try to send custom_data "contents" via x-fb-cd-contents parameter via InitiateChekout and Purchase but I get a 200 error on server side debug mode :

{"error":{"message":"Invalid parameter","type":"OAuthException","code":100,"error_subcode":2804019,"is_transient":false,"error_user_title":"Server Side Api Parameter Error","error_user_msg":"The parameter $['data'][0]['custom_data']['contents'] must be an array.","fbtrace_id":"Ack-e18nn4DSE933xa9Xv2_"}}

BUT, those parameters are well sent through client side tag :

Parameters: (4)
contents:
[{"id":"1234567890","name":"Boucles doreilles ROMY","item_price":35,"quantity":1}]
value:
35
currency:
EUR
content_type:
product

It seems that the parameter x-fb-cd-contents doesn't match the "contents" parameter or is unable to sent it correctly.

Grateful for any ideas, many thanks.

I assume you are using a GA4 tag? (this template is intended to ingest GA4 events) If so, simply use the standard GA4 'items' array (documentation <https://developers.google.com/tag-manager/ecommerce-ga4#measure_a_checkout>) and those properties will be mapped to a contents array by the template. (items[x].item_id will be mapped to contents[x].id, items[x].item_name will be mapped to contents[x].name, etc...) — Kevin O'Connor, Digital Marketing Analyst www.iDimension.com <http://www.idimension.com/?utm_id=VwkC> +1 (866) 524.3733

Yes I am using GA4 tag.

I tried the "items" parameter rather than the "x-fb-cd-contents" parameter and it worked !
I just changed some parameters in the array and everything matches perfectly --> https://prnt.sc/1qhpoih

Thank a lot for you help.
