ValueError: The last dimension of the inputs toDenseshould be defined. FoundNone.

When fine-tuning a EfficientNetB0 with my own fully connected layer I get the above error

my import looks like this import efficientnet.tfkeras as efn

and

baseModel = efn.EfficientNetB0(weights="imagenet", include_top=False) headModel = FCHeadNet.build(baseModel, len(classNames), 256)

But the error is shown in this line

headModel = Dense(D, activation="relu")(headModel)
