Health Check fail (102) and MPS fails (508)

[Akilax0]

Summary

Aria Gen 2 recordings made with profile8 with OS v22 has a StreamId 502-1 , but it is not registered in Aria Device Model. The data provider cannot label or activate it, so it is dropped. The VRS health check reports the device_info stream is missing.

Environment

• Glasses: Aria Gen 2 ("Oatmeal")
• Glasses OS: release v22, channel "Nebula OTA Public", build 5117682.1130.500 (Jun 23 2026)
• Recording profile: predefined profile8
• OS (host): Fedora 44, Python 3.12 (conda env)
• Packages:
  projectaria-client-sdk 2.4.0
  projectaria-tools 2.1.4
  projectaria-mps 1.2.3
  projectaria-vrs-health-check 1.2.1

Outputs

opening a profile8 recording ,

[VrsDataProvider][INFO]: Fail to activate streamId 502-1
[StreamIdLabelMapper][WARNING]: stream id 502-1 not found in Aria Device Model. You will not be able to get the label of this stream.

VRS health check reports

streams_match_profile: fail
ERRORS: device_info (device/oatmeal): expected 1, found 0
WARNINGS: Unmapped stream found: GPS Data Class (device/oatmeal), instance 1;
          Unmapped stream found: Time Domain Mapping Class (device/oatmeal), instance 1;
          Unmapped stream found: Battery Data Class (device/oatmeal), instance 1

aria_mps exits with error 102 locally , when healthcheck bypassed, recording encrypts and uploads successfully but server side processing then fails.

feature: SLAM          → status: FAILED, error_code: 508
feature: HAND_TRACKING → status: FAILED, error_code: 508

Steps to reproduce

• Record with predefined profile8 on Aria Gen 2 running OS v22 (~2 min, normal head motion).
• Open the VRS with projectaria-tools 2.1.4 → observe Fail to activate streamId 502-1 and the not found in Aria Device Model warning.
• Run the VRS health check → streams_match_profile fails with device_info: expected 1, found 0.
• Run aria_mps single -i .vrs --features SLAM HAND_TRACKING → local error 102; if health check is bypassed, server returns 508.

Hey @Akilax0 are you on the Project Aria Discord Community? This is an issue we have been seeing with other devices as well and we are working through this. If you are part of the discord server please let me know if you are able to start a past on the user support channel.

Hey @Akilax0 please let us know if you are part of the discord community. If not please reach out to ariaops@meta.com.

Hey @Akilax0 could you please follow these steps and report back if the health check issue is still persistent?

(a) setting up a fresh environment following the latest official Aria Gen 2 setup guide
(b) updating the Client SDK
(c) making a new recording. New recordings then contain the stream and process through MPS normally (older recordings will keep failing).

Could you please follow and check if you are able to find success following this process?

Hi ,
I have been collecting recordings during the past few days.
And I have also tried with using newer environment with updated SDK
Some recordings work , some don't .

The ones that don't work seem to be giving missing sensor readings in the recordings such as proximity and GPS . I am going to collect more recordings today and try to narrow down if there are repeated sensor recording issues.

Hey @Akilax0 thank you for reporting this. Could you please expand on how you are starting the recordings? Are you using the client sdk to start the recordings or the Companion App? Unfortunately we are not able to reproduce this issue on our end.

Also do you have multiple sets of glasses? If so could you please check if this happens on other glasses as well?

Also any information on your data collection setup would be useful as well.
