Hello,
Thanks for reaching out to the Google Ads API Team.
From what I can understand from the information you have provided, you are trying to update your Responsive Search Ad using the adGroupAds:mutate method and are returning an IMMUTABLE_FIELD error.
Since you mentioned that you were able to update this via UI, I have checked on my end and I would suggest using the ads:mutate method in updating your Responsive Search Ad. You can find more information on this method via this link (https://developers.google.com/google-ads/api/rest/reference/rest/v14/customers.ads/mutate).
If you encounter any errors, kindly provide us with the complete logs (request and response with request ID) generated on your end so we can investigate further.
You can provide it via Reply privately to the author option. If this option is not available, then send it instead on this email address googleadsa...@google.com
