Facebook Marketing connector started throwing the following error:

Tried accessing nonexisting field (cost_per_conversion_lead) on node type (AdsInsights)

It seems like the error you're encountering,

Tried accessing nonexisting field (cost_per_conversion_lead) on node type (AdsInsights)

, is due to attempting to access a field that does not exist in the

AdsInsights

stream of the Facebook Marketing connector. Based on the knowledge sources provided, there are a few relevant points to consider: 1. Field Availability: Ensure that the field

cost_per_conversion_lead

is indeed available in the Facebook Marketing API for the

AdsInsights

stream. The error suggests that this field might not be part of the

AdsInsights

stream. 2. Field Additions and Updates: There have been requests and updates to add new fields to the

AdsInsights

stream in the past. For example, [Issue #9836](https://github.com/airbytehq/airbyte/issues/9836) mentions adding new fields to the

ads_insights

stream, but

cost_per_conversion_lead

is not listed among them. 3. Configuration and Version: Ensure that you are using the correct version of the Facebook Marketing connector. There have been multiple updates and fixes to the connector, as seen in various issues like [Issue #31860](https://github.com/airbytehq/airbyte/issues/31860) and [Issue #19119](https://github.com/airbytehq/airbyte/issues/19119). To resolve this issue, you can take the following steps: 1. Verify Field Existence: Check the Facebook Marketing API documentation to confirm whether the

cost_per_conversion_lead

field exists in the

AdsInsights

stream. 2. Update Connector: Ensure that you are using the latest version of the Facebook Marketing connector. If not, update to the latest version. 3. Modify Configuration: If the field does not exist, you will need to modify your configuration to exclude the

cost_per_conversion_lead

field or replace it with the correct field name. If you continue to face issues, you might want to open a new issue on the Airbyte GitHub repository or check existing issues for similar problems. For further assistance, you can refer to the [Airbyte documentation](https://docs.airbyte.com/) or the [Facebook Marketing API documentation](https://developers.facebook.com/docs/marketing-api/). If you need more specific guidance, please provide additional details about your connector version and configuration.
