Session token not found issue on Machine provisioning Deployment on vRA

[Cyril Do]

Hi,
I encounter an issue during the Deployment process. I'm using API call only : 

1. getting the token bearer via POST /csp/gateway/am/api/login?access_token

2. Start Deployment via POST /catalog/api/items/<my catalog item id>/request and I receive a 200 OK

Deployment starts. I can see steps in GUI :

- Network allocation is OK

- Machine Allocation is OK

- Network provisionning is OK

- Machine provisionning is NOK

It fails after around 5 minutes with this issue :

 Extensibility triggered task failed. Event ID: 6f1-ff2e-30dc-9e2b. Failure: Extensibility error received for topic compute.provision.post, eventId = 'd03f1-ff2e-818a49a': [10040] SubscriberID: vro-gateway-Na5655vzW9Gv, RunnableID: 0dba and SubscriptionID: sub_ failed with the following error: com.vmware.automation.vro.gateway.common.RemoteVroGatewayException: Automation Orchestrator Gateway received error 404 NOT_FOUND for request: /sessions/exchange error: {"timestamp":"2025-03-12T23:25:56.219+0000","path":"/session-service/api/sessions/exchange","status":404,"error":"Not Found","message":"404 NOT_FOUND \"Session token not found\"","requestId":"7292","@type":"org.springframework.web.server.ResponseStatusException"}

This seems to be related API token, are you using both Access and refresh tokens ?
