Unable to create a campaign

Hello team,
We were able to deploy without any errors. However, when attempting to create a campaign, we are getting 400 error. Could you please help us resolve the error ?
Error:
{

Please try again. <HttpError 400 when requesting https://docs.googleapis.com/v1/documents/177WI3AE4J7JJY97Ob5XkrwNa5Skuno0w:batchUpdate?alt=json returned "This operation is not supported for this document".
