### Reproduction

```

from transformers import TapasTokenizer, TFTapasModel
import pandas as pd

tokenizer = TapasTokenizer.from_pretrained("google/tapas-base")
model = TFTapasModel.from_pretrained("google/tapas-base")

data = {
    "Actors": ["Brad Pitt", "Leonardo Di Caprio", "George Clooney"],
    "Age": ["56", "45", "59"],
    "Number of movies": ["87", "53", "69"],
}
table = pd.DataFrame.from_dict(data)
queries = ["How many movies has George Clooney played in?", "How old is Brad Pitt?"]

inputs = tokenizer(table=table, queries=queries, padding="max_length", return_tensors="tf")
outputs = model(**inputs)

last_hidden_states = outputs.last_hidden_state

model.save_pretrained("test",saved_model=True)
```


```

### Expected behavior

It is supposed to make a SavedModel but instead, I get this error mentioned above. The SavedModel is needed for TensorFlow Serving .
Following merging of #18153 the reproduction snippet runs on main without error.
