2 months ago Hey, @NightRang3r! I'm here to assist you with any bugs, questions, or contributions. Let's tackle this issue together while we wait for a human maintainer.
To resolve the "Unsupported message type: <class 'dict'>" error when building the Ollama component in Langflow, ensure that the metadata parameter, which is expected to be a dictionary, is correctly handled. The error suggests that a dictionary is being passed where it is not expected.
Here is the relevant part of the code:
llm_params = {
"base_url": self.base_url,
"model": self.model,
"mirostat": mirostat_value,
"format": self.format,
"metadata": self.metadata, # Ensure this is a dictionary
"tags": self.tags.split(",") if self.tags else None,
"mirostat_eta": mirostat_eta,
"mirostat_tau": mirostat_tau,
"num_ctx": self.num_ctx or None,
"num_gpu": self.num_gpu or None,
"num_thread": self.num_thread or None,
"repeat_last_n": self.repeat_last_n or None,
"repeat_penalty": self.repeat_penalty or None,
"temperature": self.temperature or None,
"stop": self.stop_tokens.split(",") if self.stop_tokens else None,
"system": self.system,
"template": self.template,
"tfs_z": self.tfs_z or None,
"timeout": self.timeout or None,
"top_k": self.top_k or None,
"top_p": self.top_p or None,
"verbose": self.verbose,
}
# Remove parameters with None values
llm_params = {k: v for k, v in llm_params.items() if v is not None}
try:
output = ChatOllama(**llm_params) # Ensure ChatOllama can handle the metadata dictionary
except Exception as e:
raise ValueError("Could not initialize Ollama LLM.") from eEnsure that the metadata parameter is correctly formatted as a dictionary before passing it to ChatOllama. If ChatOllama does not support a dictionary for metadata, you may need to modify the ChatOllama class or adjust how metadata is being used.
Additionally, the metadata dictionary should have the following structure:
"metadata": {
"display_name": "Metadata",
"info": "Metadata to add to the run trace.",
"advanced": True,
}Make sure that the ChatOllama class is designed to handle this structure appropriately [1][2][3][4].
