Debug common errors

Error
ConversionUploadError.INVALID_CONVERSION_ACTION_TYPE	The specified conversion action has a type that is not valid for enhanced conversions for leads. Make sure the ConversionAction specified in your upload request has type UPLOAD_CLICKS.
ConversionUploadError.NO_CONVERSION_ACTION_FOUND	The specified conversion action is either not enabled or cannot be found within the uploading customer. Make sure the conversion action in your upload is enabled and is owned by the customer sending the upload request.
ConversionUploadError.CLICK_CONVERSION_ALREADY_EXISTS	There is already a click conversion with the specified click ID and conversion_date_time. Make sure the conversion_date_time is unique or the click conversion specifies a unique order_id.
ConversionUploadError.CUSTOMER_NOT_ENABLED_ENHANCED_CONVERSIONS_FOR_LEADS	Make sure you've turned on enhanced conversions for leads in your conversion settings. Find instructions for this in the prerequisites guide.
ConversionUploadError.DUPLICATE_ORDER_ID	Make sure order IDs are unique across your uploaded conversions.
ConversionUploadError.CLICK_NOT_FOUND	No click was found that matched the provided user identifiers. The Google Ads API only returns this error if debug_enabled is true on the UploadClickConversionsRequest. Note: Treat this error as a warning unless it occurs with the majority of your conversions. Starting in v15, if a conversion encounters this warning, the Google Ads API includes it in the successful_event_count of your offline data diagnostics. On versions prior to v15, the successful_event_count excludes conversions with this warning. The Google Ads API includes an entry for CLICK_NOT_FOUND in the alerts collection in all available versions of the API so you can monitor the frequency of this warning. This error is expected if the click is not from a Google Ads campaign. Other possible causes are as follows: The uploading customer is different from the Google Ads conversion customer. Tagging is not correctly set up for your lead form. The uploaded data has not been correctly normalized and hashed. In rare instances where the uploading customer is different from the Google Ads conversion customer, this error can mean that the uploading customer has accepted the customer data terms, but the serving customer has not.
