**Description:** This PR addresses the `TypeError: sequence item 0: expected str instance, FluentValue found` error when invoking `WikidataQueryRun`. The root cause was an incompatible version of the `wikibase-rest-api-client`, which caused the tool to fail when handling `FluentValue` objects instead of strings. The current implementation only supports `wikibase-rest-api-client<0.2`, but the latest version is `0.2.1`, where the current implementation breaks. Additionally, the error message advises users to install the latest version: [code reference](https://github.com/langchain-ai/langchain/blob/master/libs/community/langchain_community/utilities/wikidata.py#L125C25-L125C32). Therefore, this PR updates the tool to support the latest version of `wikibase-rest-api-client`. Key changes: - Updated the handling of `FluentValue` objects to ensure compatibility with the latest `wikibase-rest-api-client`. - Removed the restriction to `wikibase-rest-api-client<0.2` and updated to support the latest version (`0.2.1`). **Issue:** Fixes [#24093](https://github.com/langchain-ai/langchain/issues/24093) – `TypeError: sequence item 0: expected str instance, FluentValue found`. **Dependencies:** - Upgraded `wikibase-rest-api-client` to the latest version to resolve the issue. --------- Co-authored-by: peiwen_zhang <peiwen_zhang@email.com> Co-authored-by: Erick Friis <erick@langchain.dev> Co-authored-by: Chester Curme <chester.curme@gmail.com>
