2 days ago Hey @ugyuji! I'm here to help you with any bugs, questions, or contributions you have for our project. Let's squash those bugs together! 😊
I found a similar issue that might help you resolve the error "Failed to invoke tool: unhashable type: 'dict'". The error occurs because the tool_parameters dictionary is being used in a context where a hashable type is required. In Python, dictionaries are not hashable and cannot be used as keys in other dictionaries or added to sets.
To resolve this issue, ensure that tool_parameters or any of its contents are not being used in a way that requires them to be hashable. For example, if tool_parameters is being used as a key in another dictionary, you should convert it to a hashable type, such as a tuple of key-value pairs.
Here is the relevant part of the code for reference:
class CrawlTool(BuiltinTool):
def _invoke(self, user_id: str, tool_parameters: dict[str, Any]) -> ToolInvokeMessage:
app = FirecrawlApp(
api_key=self.runtime.credentials["firecrawl_api_key"], base_url=self.runtime.credentials["base_url"]
)
scrapeOptions = {}
payload = {}
wait_for_results = tool_parameters.get("wait_for_results", True)
payload["excludePaths"] = get_array_params(tool_parameters, "excludePaths")
payload["includePaths"] = get_array_params(tool_parameters, "includePaths")
payload["maxDepth"] = tool_parameters.get("maxDepth")
payload["ignoreSitemap"] = tool_parameters.get("ignoreSitemap", False)
payload["limit"] = tool_parameters.get("limit", 5)
payload["allowBackwardLinks"] = tool_parameters.get("allowBackwardLinks", False)
payload["allowExternalLinks"] = tool_parameters.get("allowExternalLinks", False)
payload["webhook"] = tool_parameters.get("webhook")
scrapeOptions["formats"] = get_array_params(tool_parameters, "formats")
scrapeOptions["headers"] = get_json_params(tool_parameters, "headers")
scrapeOptions["includeTags"] = get_array_params(tool_parameters, "includeTags")
scrapeOptions["excludeTags"] = get_array_params(tool_parameters, "excludeTags")
scrapeOptions["onlyMainContent"] = tool_parameters.get("onlyMainContent", False)
scrapeOptions["waitFor"] = tool_parameters.get("waitFor", 0)
scrapeOptions = {k: v for k, v in scrapeOptions.items() if v not in (None, "")}
payload["scrapeOptions"] = scrapeOptions or None
payload = {k: v for k, v in payload.items() if v not in (None, "")}
crawl_result = app.crawl_url(url=tool_parameters["url"], wait=wait_for_results, **payload)
return self.create_json_message(crawl_result)Ensure that tool_parameters is not being used in a way that requires it to be hashable, and the error should be resolved. For instance, the scrapeOptions and payload dictionaries are filtered to remove None or empty values before being used, which helps avoid such issues [1][2][3].
Additionally, you might find it helpful to look at similar issues and discussions:
- Expecting value: line 1 column 1 (char 0) (Unsolved discussion) [4]
- 0.8.3 parallel Workflow run failed (Closed issue) [5]
- raise err when run workflow as tool (Closed issue) [6]
