Forge Viewer - Convert-utils for glTF not working

Question

We are trying to seek forge-convert-utils in order to get a list of the gltf's from the urns sent. When we reach to construct a new ManifesterHelper(), this returns undefined, forcing the loop to advance for next urn (with the obvious same result).

 urnsPerProject.forEach(async urn => {
   try {
     const auth = {
       client_id: process.env.FORGE_CLIENT_ID,
       client_secret: process.env.FORGE_SECRET
     }

     const parsedUrn = Buffer.from(urn).toString('base64')

     const mdClient = new ModelDerivativeClient(
       auth,
       'https://developer.api.autodesk.com',
       Region.EMEA
     )

     const helper = new ManifestHelper(await mdClient.getManifest(parsedUrn))
     const derivatives = helper.search({ type: 'resource', role: 'graphics' })

     const readerOptions = {
       log: console.log
     }

     const writerOptions = {
       deduplicate: true,
       skipUnusedUvs: true,
       center: false,
       log: console.log
     }

     const writer = new GltfWriter(writerOptions)

     const filteredDerivatives = derivatives.filter(derivative => {
       // eslint-disable-next-line @typescript-eslint/ban-ts-comment
       // @ts-ignore
       return derivative.mime === 'application/autodesk-svf'
     })

     for (const derivative of filteredDerivatives) {
       const reader = await SvfReader.FromDerivativeService(
         urn,
         derivative.guid,
         auth
       )

       const scene = await reader.read(readerOptions)
       console.log('scene', scene)
     }
   } catch (error) {
     console.error('error', error)
   }
 })

error: requested resource does not exist

debugged parsed urn parameter

Answer 1

Problem in here was solved!

1st - I missed to replace the '/' by '_' at the base64 parsedUrn

const parsedUrn = Buffer.from(urn).toString('base64').replace('/', '_')

2nd - I was choosing EMEA as Region, but I had to pass US

Great thx to #PetrBroz from #Autodesk
