Hi, thanks for reaching out. It looks like you're trying to compose a model trained with a prior version of the API. This is not supported because there are breaking changes from v2.1 and v3.0. Please review the following document for more details.

• To compose a model trained with a prior version of the API (v2.1 or earlier), train a model with the v3.0 API using the same labeled dataset. That addition will ensure that the v2.1 model can be composed with other models.
• Models composed with v2.1 of the API will continue to be supported, requiring no updates.
• The limit for maximum number of custom models that can be composed is 100.
