DynamicBoneReplacer.csでエラーが出てVRCアバターからVRMに変換できない

[misumisumi]

生じている問題

DynamicBoneReplacer.cs関連でエラーが出ているようでVRMモデルに変換できない

期待する動作

VRChatアバターからVRMモデルへの正常な変換

再現手順

• Dynamic Boneが設定されたアバターを対象にしてExport VRM file from VRChat avatarを実行する
• 複数衣装でも単一の衣装(unitypackagesに設定されているprefab)のどちらでも下記のエラーが表示されました

環境

• VRCSDK3-AVATAR-2021.06.03.14.57_Public
• Unity ver 2018.4.20f1
• VRM Converter for VRChat 26.0.0
• OS: windows10 および mac(mono)

追記

• Quest Toolsを使用してDynamic Boneを取り除いたアバターは正常に変換がされました
• エラーログ的に関係ないかと思いますが、シェーダーはPoiyomi Shaderを使用しています
