constructing the request for retrieveFromDataset: reject non-finite values and
values outside the supported score range by throwing ConfigurationError, and
only apply Number conversion after validation. Keep score_threshold_enabled
consistent with the validated value.
- Line 28: Update the datasetId description in the query knowledge base action
to identify the value as a UUID and include an inline example, while retaining
the instruction to obtain valid IDs from List Knowledge Bases.
In `@components/dify/dify.app.mjs`:
- Line 26: Update the Dify connection credentials to include separate
application and knowledge-base API keys, then adjust _headers() and its callers
so app endpoints use the application key while listDatasets() and
retrieveFromDataset() use the dataset key. Ensure each endpoint group sends the
appropriate Bearer credential instead of always using this.$auth.api_key.

Dify API reference app API key dataset knowledge base API key separate credentials
💡 Result:
In Dify, Application API keys and Knowledge Base (dataset) API keys are separate credentials with distinct scopes and management locations [1][2][3]. Key differences and management details: 1. Application API Keys: These are scoped to a specific application (Chatbot, Workflow, Agent, etc.) [1][4]. They allow you to interact with that specific app's interface (e.g., sending chat messages or triggering workflows) [1][5]. You manage these keys by navigating to the specific application in Dify and selecting API Access [5][4]. 2. Knowledge Base (Dataset) API Keys: These keys are used for programmatic management of your knowledge bases, including uploading documents, managing chunks, and retrieving knowledge metadata [6][7]. A single Knowledge Base API key has access to all knowledge bases visible to the account that created it [6][8][7]. You manage these keys by navigating to the Knowledge section in Dify and clicking Service API in the top-right corner [6][9][7]. Both types of keys use the same HTTP Bearer Authentication mechanism, where the key is passed in the Authorization header (e.g., Authorization: Bearer {API_KEY}) [10][4]. Because these credentials provide access to your AI services and data, Dify strictly advises that they should always be stored server-side and never exposed in client-side code [6][1][4]. You can enable or disable API access for individual knowledge bases via the API Access settings located within each specific knowledge base [6][7].

Use separate credentials for app and dataset endpoints.
_headers() always sends $auth.api_key, including from listDatasets() and retrieveFromDataset(). Dify requires distinct application and knowledge-base API keys, so add both fields to the Dify connection and select the correct key for each endpoint group.

from the user parameter so user remains required when fetching message history.
Preserve the existing conversationId handling and response behavior.

- Add `ai: "optimized"` to Dify actions. - Update `user` field descriptions in `list-conversations` and `list-messages` to clarify that omitting the value results in an empty response rather than an error.

Keep shared user metadata in components/dify/dify.app.mjs.
Both actions locally redefine the shared user prop description. This can cause descriptions and examples to drift between actions.
components/dify/actions/list-conversations/list-conversations.mjs#L22-L22: remove the local description and use the shareduserpropDefinition; place the identifier guidance and example incomponents/dify/dify.app.mjs.components/dify/actions/list-messages/list-messages.mjs#L27-L27: remove the local description and use the same shareduserpropDefinition; keep the message-history guidance incomponents/dify/dify.app.mjs.
As per path instructions, shared props must use the app file's propDefinitions, and component files must not duplicate prop descriptions.
