   Thank you for the report. Can you provide the options used for the request?

   This error is reported by a customer. I cannot duplicate it using personal security keys.
   obj.dwCredLargeBlobStatus is always zero in my setup.
   The options used by our app (it does not support largeBlob) have the following format

   {
     "publicKeyCredentialRequestOptions" : {
       "challenge" : "boyuGSfORAEdDibXY6K3IASF5hYRF9M-DZkiI0FswAM",
       "hints" : [ ],
       "rpId" : "aaa.com",
       "allowCredentials" : [ {
         "type" : "public-key",
         "id" : "jcqfO4ek2PGTCdgWxf6wj-mhMhB8Fxd1og-I1bAh6N36CrDs6lrUtrd-ELRxhMFcgomk5zyxLHXnxRKVJpWEWA"
       } ],
       "userVerification" : "discouraged",
       "extensions" : {
         "appid" : "https://aaa.com"
       }
     },
     "username" : "aaa@aaa.com"
   }
