I'm trying to generate images using the imagen-3.0-generate-002 model by running a python script in my github workflow and I'm encountering the following error:
❌ Error generating image: 429 Quota exceeded for aiplatform.googleapis.com/generate_content_requests_per_minute_per_project_per_base_model with base model: imagen-3.0-generate. Please submit a quota increase request. https://cloud.google.com/vertex-ai/docs/generative-ai/quotas-genai.
I'm able to make normal text requests to vertex ai without issues. I've even tried to request image generation in isolation so as to not hit rate limits. My project quota indicates a value of 10 with none used. I also have billing enabled. Why am I still getting the error? My request code is below:

try:
print("\n🎨 Initializing AI image generation...")
# Initialize Vertex AI
project_id = os.getenv('GCP_PROJECT_ID')

vertexai.init(project=project_id, location=location)

response = image_model.generate_content(
