Is there a limit to the number of fields in a custom model?

Manaloto, John [IBM] 16

I have a custom model that fails to build with the following error:

ModelBuildError: Could not build the model: Can't find valid fields.json file in provided dataset.

It was working with 315 text fields. After adding 54 more fields, it consistently fails to build/train with the above error. Is there a limit to the number of fields for a custom model? I receive the same error with either neural or template model.

Hi, any update on this issue? I face the same error since I have a lot of fields. I could train the model without any problem before that. Thank you!

Same problem. The training fails with either

ModelBuildError: Could not build the model: Can’t find valid fields.json file in provided dataset.

or

InternalServerError: An unexpected error occurred.

since we have a lot of keys (511).
