Cause (Documented platform behavior): Agent Engine only accepts cpu in {1,2,4,6,8}, memory in Gi below 32Gi, with minimum CPU per memory size.
Fix status: documented_behavior
Other error fragments:
- is too large. Must be smaller than 32Gi.
- resource_limits must contain 'cpu' and 'memory' keys.
- must be a string ending with 'Gi'. Got

Problem details
- Observed symptom
- Agent Engine create/update fails locally on resource_limits.
- Context
- Product: Vertex AI SDK for Python (google-cloud-aiplatform) Component: vertexai._genai agent_engines config Operation: client.agent_engines.create(config={'resource_limits': {...}}) Affected versions: observed in google-cloud-aiplatform 2.2.0 source; introduction version unknown Environment: unknown Exception: ValueError, KeyError Packages: google-cloud-aiplatform source at 2.2.0 (main 6da2b9b) Trigger: Setting cpu/memory values outside allowed combinations (e.g. memory as '4096Mi', cpu 3, memory >=32Gi, high memory with too few CPUs).

solution · Revision 1
Proposed fix: [Vertex AI Agent Engine] resource_limits validation: 'Memory size of X is too large. Must be smaller than 32Gi.' / 'requires at least N CPUs' / cpu must be one of 1, 2, 4, 6, 8
Recommended action: Specify both keys, cpu from the allowed set, memory as '<n>Gi' < 32Gi and meet the min CPU for the memory size.
Option: Use allowed values [evidence: documented_workaround]
Steps:
1. resource_limits={'cpu':'4','memory':'8Gi'}
Expected: Validation passes
Evidence basis (self-declared by the contributing chat client): untested.
