Issue: LinkedIn API POST requests failing with version parsing bug on Maton gateway.
Details:
• GET requests work fine with LinkedIn-Version: 202603
• POST requests to /linkedin/rest/ugcPosts reject all version headers
• Gateway converts LinkedIn-Version: 202603 → 20250301 (invalid format)
• Tested versions: 202504, 202505, 202502, 202603 — all fail with same error
• Connection status: ACTIVE
• Added X-Restli-Protocol-Version: 2.0.0 per LinkedIn API spec — still fails
Error Response:
{
“status”: 426,
“code”: “NONEXISTENT_VERSION”,
“message”: “Requested version 20260301 is not active”
}
Request: Can the gateway POST endpoint be reviewed? It appears to be incorrectly parsing the LinkedIn-Version header format for POST operations.
