### Checked other resources

- [X] I added a very descriptive title to this issue.

- [X] The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

### Example Code

```python
from langchain_community.embeddings import JinaEmbeddings, LlamaCppEmbeddings, TensorflowHubEmbeddings, GooglePalmEmbeddings
```
