XrResult failure [XR_ERROR_PATH_UNSUPPORTED]

[Harry79]

When running the BasicXrApp on the HP Reverb G2 an exception is raised:

  ERROR (OpenXR) : [xrSuggestInteractionProfileBindings] Suggested binding '/user/hand/right/input/trigger/value' is not supported by interaction profile '/interaction_profiles/hp/mixed_reality_controller'.
  Ausnahme ausgelöst bei 0x00007FFFD9624ED9 in BasicXrApp_win32.exe: Microsoft C++-Ausnahme: msxr::XrResultException bei Speicherort 0x000000D5D54FE268.

I commented out the following block, then the application works:

            if (m_optionalExtensions.HPMRControllerSupported)
            {
                std::vector<XrActionSuggestedBinding> bindings;
                bindings.push_back({m_placeAction.Get(), GetXrPath("/user/hand/right/input/trigger/value")});
                bindings.push_back({m_placeAction.Get(), GetXrPath("/user/hand/left/input/trigger/value")});
                bindings.push_back({m_poseAction.Get(), GetXrPath("/user/hand/right/input/grip/pose")});
                bindings.push_back({m_poseAction.Get(), GetXrPath("/user/hand/left/input/grip/pose")});
                bindings.push_back({m_vibrateAction.Get(), GetXrPath("/user/hand/right/output/haptic")});
                bindings.push_back({m_vibrateAction.Get(), GetXrPath("/user/hand/left/output/haptic")});
                bindings.push_back({m_exitAction.Get(), GetXrPath("/user/hand/right/input/squeeze/value")});
                bindings.push_back({m_exitAction.Get(), GetXrPath("/user/hand/left/input/squeeze/value")});

                XrInteractionProfileSuggestedBinding suggestedBindings{XR_TYPE_INTERACTION_PROFILE_SUGGESTED_BINDING};
                suggestedBindings.interactionProfile = GetXrPath("/interaction_profiles/hp/mixed_reality_controller");
                suggestedBindings.suggestedBindings = bindings.data();
                suggestedBindings.countSuggestedBindings = (uint32_t)bindings.size();
                CHECK_XRCMD(xrSuggestInteractionProfileBindings(m_instance.Get(), &suggestedBindings));
            }

            // Set up suggested bindings for the microsoft/hand_interaction profile.
            if (m_optionalExtensions.MsftHandInteractionSupported)
            {
                std::vector<XrActionSuggestedBinding> bindings;
                bindings.push_back({m_placeAction.Get(), GetXrPath("/user/hand/right/input/select/value")});
                bindings.push_back({m_placeAction.Get(), GetXrPath("/user/hand/left/input/select/value")});
                bindings.push_back({m_poseAction.Get(), GetXrPath("/user/hand/right/input/grip/pose")});
                bindings.push_back({m_poseAction.Get(), GetXrPath("/user/hand/left/input/grip/pose")});
                bindings.push_back({m_exitAction.Get(), GetXrPath("/user/hand/right/input/squeeze/value")});
                bindings.push_back({m_exitAction.Get(), GetXrPath("/user/hand/left/input/squeeze/value")});

                XrInteractionProfileSuggestedBinding suggestedBindings{XR_TYPE_INTERACTION_PROFILE_SUGGESTED_BINDING};
                suggestedBindings.interactionProfile = GetXrPath("/interaction_profiles/microsoft/hand_interaction");
                suggestedBindings.suggestedBindings = bindings.data();
                suggestedBindings.countSuggestedBindings = (uint32_t)bindings.size();
                CHECK_XRCMD(xrSuggestInteractionProfileBindings(m_instance.Get(), &suggestedBindings));
            }

Are these controls supposed to be supported by the HP Reverb G2? In case not, the code should check for the device and probably not call the functions.

There's a fix recently addressed this problem in our 108 runtime release. Could you please try the 108 preview runtime to see if this works here?

The sample code here were correct. It was our API runtime didn't behave correctly when the user doesn't have any G2 controller turned on when launching the app. The mentioned fix above is to address this issue.

I confirm, the fix works for me. Thanks!
