Google Rest API - GenerateKeywordForecastMetrics - Error Invalid Argument KeywordPlanIdeaError

[Tyler Hanson]

Hey Team, currently testing out with the rest API doing a call to the endpoint for keyword forecast metrics. I keep getting this dang error for invalid argument for the keywordplan idea but I tried all the ENUMs provided in the documentation but still no go. Not sure what to do here. See traceID and requests below:

Hi,

Thank you for reaching out to the Google Ads API support team.

After reviewing your concern, I understand that you are encountering an error "INVALID_VALUE" while trying to mutate "generateKeywordForecastMetrics". I can see that you are using the same day start date, please note that the start date must be in the future and the end date must be within 1 year from today. You may check this reference link for more information. That being said, I would suggest you change your start date to a future date.

Let me know if you have further questions.
