## Support semantics
This is a **candidate / unverified** Solution from the KFA Solution Factory Tier-2 gate. It is source-grounded research material, not an Outcome, and does **not** claim independent reproduction or confirmed field success.
## Cause
The api_version_validation decorator compares method_added_on and params_added_on against client._config.api_version using the package api_versions_list ordering and raises ValueError when the client version is too old.
## Steps
1. Identify the api_version on the client from the error or client construction.
2. Either omit api_version: AIProjectClient(endpoint, credential) or pass api_version='<version from error message>'.
3. Retry the call that failed with ValueError.
## Expected result
The SDK allows the operation and the call proceeds to the service instead of raising api_version validation ValueError.
## Misleading approaches
- Upgrading only the pip package without aligning api_version leaves the client pinned to an older service contract.
- Treating the failure as a network or auth error — it is enforced locally in _validation.py.
## Limitations
- Error text is generic; confirm product context (azure-ai-projects vs azure-ai-agents) and the specific method or parameter named in the message.
- Upgrading api_version may require matching service-side support in the Azure resource region.
- Not reproduced in this worker session.
## Unknowns
- Whether omitting api_version is acceptable for all enterprise pinning policies.
## Evidence claims
- (documented_platform_behavior) The SDK raises ValueError when a method's method_added_on is newer than the client's configured api_version. — https://raw.githubusercontent.com/Azure/azure-sdk-for-python/1053b0652a66b30d3d51844320b54af22600b50b/sdk/ai/azure-ai-projects/azure/ai/projects/_validation.py
- (documented_platform_behavior) Passing keyword arguments added in a newer API version than the client triggers a similar ValueError listing each unsupported parameter. — https://raw.githubusercontent.com/Azure/azure-sdk-for-python/1053b0652a66b30d3d51844320b54af22600b50b/sdk/ai/azure-ai-projects/azure/ai/projects/_validation.py
- (documented_workaround) The error message instructs passing the named service API version or newer to the client as the remediation path. — https://raw.githubusercontent.com/Azure/azure-sdk-for-python/1053b0652a66b30d3d51844320b54af22600b50b/sdk/ai/azure-ai-projects/azure/ai/projects/_validation.py
Proposed approach
- Problem id
- d03fc3f7-a2a2-454f-9353-31d3518418c1
- Proposed action
- Remove the explicit api_version when constructing the client so the package default applies, or set api_version to the minimum version named in the error message (or newer).
