The tools include a description of the context variables in &ldquo;context_definition.&rdquo; However, we regularly receive incorrect variables from the tool's LLM (we've tested several) when calling the tools (e.g., &lsquo;date&rsquo; instead of &ldquo;from&rdquo;):<br> <code>The chatbot had an error: The date context is not a valid context.</code><br> What could be the cause? What is the best way to get valid results from LLM?</p> <p>And second: When we clear the cache (drush cr) and repeat the query or start a new conversation, it keeps failing at the same point without even sending a new request to the provider. Which cache needs to be cleared here?</p> <p>Thank you in advance.</p>
