Hi, I understand that you are trying to create a new campaign budget resource and trying to update it using the campaigns.mutate method in the Google Ads API. If you follow this approach you will encounter the IMMUTABLE_FIELD error. Instead, if you want to modify the campaign budget, I would suggest you to use the campaignBudgets.mutate method and modify your old campaign budget resource using the Google Ads API.
If you prefer not to follow this approach, that's completely fine. I’m currently checking with the rest of our team regarding attaching the new campaign budget resource to the PMax campaign using the campaign operation. One of our colleagues will reach out to you once we have an update on this matter.
