Description

Sometimes, when a user imports a GLTF material asset and the viewer automatically opens the material editor, the viewer attempts to open the material asset from the CDN prematurely, which has the effect of:

• Getting a 404 from the CDN, triggering an "Alert: Unable to load material".
• Viewer opens a material editor floater of the new material, which shows all textures missing

If the user closes the material editor and reopens the material from inventory, the editor shows that the material was, in fact, imported correctly with the appropriate materials.

This bug appears to be a race condition in which the viewer tries to fetch the material from the CDN before it's ready.

Reproduction steps

1. Obtain some GLTF materials - I used Avocado.gltf and AntiqueCamera.gltf from https://github.com/KhronosGroup/glTF-Sample-Assets/
2. Login with the viewer
3. Open Upload -> Material, and import a material
4. If multiple materials are referenced in the GLTF file, opt to import them all (this should increase the chance of hitting the bug)
5. Note if any errors appear

Expected results:
Successful material import every time, with the viewer showing the newly-imported materials in the material editor, including populated texture thumbnails.

Actual results:

• Sometimes (not sure of the repro rate), the viewer shows Alert: Unable to load material.\nPlease try again. error, triggered by a 403 when trying to GET a material asset from the CDN.
• When this error occurs, the viewer opens a material editor floater for the new material, with all textures missing - looking like a real failure
• If the user closed the floater and reopens the material from agent inventory, it appears correctly with all textures populated

Example case:

• I used the Avocado and AntiqueCamera gltf materials, after verifying that they use 2k textures for all materials.
• My first upload, of Avocado.gltf, was successful.
• My second upload about 30 seconds later, of AntiqueCamera.gltf (all materials) appeared to fail partially:
  • 'AntiqueCamera (tripod)' material uploaded successfully. A material asset was created in my inventory for it, and has populated textures.
  • 'AntiqueCamera (camera)' material hit this issue, with a "Alert: Unable to load material", apparently triggered by a 403 from the CDN of asset 2b2af3ba-e95b-d899-756a-03635eb9e25e
• The 3 textures from 'AntiqueCamera (camera)' were actually uploaded successfully
• When I closed and reopened the (seemingly empty) 'AntiqueCamera (camera)' material in the inventory browser, it appeared properly with all 3 of its associated maps.
• The successfully imported 'AntiqueCamera (camera)' material has asset_id b8891f4e-3d44-e17d-f73f-bdc247fc5ff9, which is distinct from the asset_id that triggered the Alert message. Was the viewer trying to load the wrong asset_id?

Here are the relevant viewer logs:
