AgentEngineSandboxCodeExecutor uses wrong JSON field names for stdout/stderr #3690
Description
Description
The AgentEngineSandboxCodeExecutor class has two field name mismatches that cause it to fail silently:
Bug 1: stdout/stderr field names
Location: agent_engine_sandbox_code_executor.py lines 138-140
| Code expects | API returns |
|---|---|
| stdout | msg_out |
| stderr | msg_err |
Result: CodeExecutionResult.stdout and stderr are always empty.
Bug 2: Input file field names
Location: agent_engine_sandbox_code_executor.py lines 113-119
| Code sends | API expects |
|---|---|
| contents | content |
| mimeType | mime_type |
Result: Input files are not readable in the sandbox, causing errors like pandas.errors.EmptyDataError: No columns to parse from file.
