Chain builder API not working with Claude?

[BWStearns]

@prabirshrestha is there an idiomatic way to include a system prompt with Claude just using the llm API? I am struggling with the chain builder API.

I'm getting Error invoking Claude: LLMError(RequestError(reqwest::Error { kind: Decode, source: Error("missing field content", line: 1, column: 205) })) with the following:

    let spelling_and_grammar_prompt = "bunch of instructions: {{input}}"
    let full_prompt = message_formatter![
        fmt_message!(Message::new_system_message("Reply with a boolean: 'true' or 'false'.")),
        fmt_template!(HumanMessagePromptTemplate::new(template_jinja2!(
            spelling_and_grammar_prompt,
            "input"
        )))
    ];

    let claude = LLMChainBuilder::new()
        .prompt(full_prompt)
        .llm(claude::Claude::default()
            .with_options(claude_options)
            .with_model("claude-3-haiku-20240307"))
        .build()
        .unwrap();

    let input_variables = prompt_args! {
        "input" => &full_spelling_and_grammar_prompt,
    };

    let spelling_grammar_resp = claude.invoke(input_variables).await;

Hi @BWStearns I think you are sending in the input variables the "bunch of instructions: {{input}}" when you should just send the 'input'
example :

 let spelling_and_grammar_prompt = "Is Lima the capital of: {{input}}";
    let full_prompt = message_formatter![
        fmt_message!(Message::new_system_message("Reply with a boolean: 'true' or 'false'.")),
        fmt_template!(HumanMessagePromptTemplate::new(template_jinja2!(
            spelling_and_grammar_prompt,
            "input"
        )))
    ];

    let claude = LLMChainBuilder::new()
        .prompt(full_prompt)
        .llm(claude::Claude::default()
            .with_options(claude_options)
            .with_model("claude-3-haiku-20240307"))
        .build()
        .unwrap();

    let input_variables = prompt_args! {
        "input" => "Peru"
    };

    let spelling_grammar_resp = claude.invoke(input_variables).await;
