- Introduced a new node, DownloadS3FileNode, for downloading files from S3. - Updated main.py to include the new node in the runtime configuration. - Removed unused 'store' field from NodeTemplate model in state-manager. This enhances the cloud storage functionality by allowing file downloads directly from S3.

Summary of Changes
Hello @NiveditJain, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request primarily focuses on enhancing the cloud-storage-runtime by adding a new capability to download files from S3. Concurrently, I've made significant updates to the exospherehost SDK to standardize data handling within nodes, ensuring that all inputs, outputs, and secrets are strictly string-based. This change is accompanied by relevant documentation updates and new validation rules. Additionally, I've performed some general cleanup by removing unused components and simplifying a core data model in the state manager.
Highlights
- New S3 Download Node: I've introduced a new
DownloadS3FileNodewithin thecloud-storage-runtime. This node provides functionality to download specific files from an S3 bucket, requiring the bucket name, file key, and AWS credentials. - Enforced String-Only Data Model for Nodes: I've updated the
exospherehostSDK to enforce a strict string-only data model forInputs,Outputs, andSecretsfields in nodes. This change is reflected in theREADME.mdwith updated examples and new validation logic in the runtime. - Codebase Cleanup and Refactoring: I've removed the
Statusenum and thesample.pyfile from thepython-sdkto streamline the codebase. - NodeTemplate Model Simplification: I've removed the
storefield from theNodeTemplatemodel in thestate-managerto simplify the data structure. - Version Update: I've bumped the
exospherehostSDK version to0.0.7b5.

Code Review
This pull request introduces version 0.0.7b5, which includes a new DownloadS3FileNode for the cloud storage runtime and enforces a string-only data model for node Inputs, Outputs, and Secrets in the Python SDK. The SDK's README.md has been updated to reflect this significant change. My review focuses on a critical bug in the new S3 download node, a potential issue in a code example in the README, and opportunities for code simplification and robustness. Overall, the changes are a good step towards simplifying the data model, but a few areas need attention to ensure correctness and maintainability.

11-14: Good clarification on node ordering—resolves the earlier nit.Explicitly noting that execution is orchestrated by the state manager addresses the prior comment about implicit ordering.

26-27: Tighten phrasing in the Important noteConsider changing “parse that string within your node” to “parse it within your node” for concision. Spacing looks good now with the added blank line.
-> Important: In v1, all fields in `Inputs`, `Outputs`, and `Secrets` must be strings. If you need to pass complex data (e.g., JSON), serialize the data to a string first, then parse that string within your node. +> Important: In v1, all fields in `Inputs`, `Outputs`, and `Secrets` must be strings. If you need to pass complex data (e.g., JSON), serialize the data to a string first, then parse it within your node.
76-76: Link to enforcement details or add a short migration noteAdd a pointer to where this is enforced (runtime validation) or a brief migration workflow from non-string models to v1 to reduce confusion.
Would you like me to draft a short “Migration to v1 (string-only models)” subsection and reference the runtime validation check?
109-114: Call out numeric-string expectation for max_lengthSince Inputs are strings, users might pass non-numeric max_length. Add a brief guard/remark to set expectations before converting to int.
Example:
- “max_length must be a numeric string (e.g., '100').”
116-119: Safely parse max_length with a clear errorAvoid confusing runtime errors if max_length is non-numeric.
- max_length = int(self.inputs.max_length) - result = self.inputs.text[:max_length] - return self.Outputs(result=result, length=str(len(result))) + try: + max_length = int(self.inputs.max_length) + except ValueError as e: + raise ValueError("Inputs.max_length must be a numeric string") from e + result = self.inputs.text[:max_length] + return self.Outputs(result=result, length=str(len(result)))
167-171: Raise for HTTP errors to avoid serializing error payloadsCall raise_for_status() so non-2xx responses don’t flow through as “success”.
async with httpx.AsyncClient() as client: http_response = await client.post( f"{self.secrets.api_endpoint}/process", headers=headers, json={"user_id": self.inputs.user_id, "query": self.inputs.query} ) + http_response.raise_for_status()
173-182: Prefer text, then safely fall back to JSON if emptyCurrent logic prioritizes JSON even when text is available and catches broad exceptions. Prefer text first; if empty, try JSON; catch ValueError only.
- # Serialize body: prefer JSON if valid; fallback to text or empty string - response_text = http_response.text or "" - if response_text: - try: - response_str = json.dumps(http_response.json()) - except Exception: - response_str = response_text - else: - response_str = "" + # Serialize non-string data to string (prefer text; fall back to JSON if empty and valid) + response_str = http_response.text + if not response_str: + try: + response_str = json.dumps(http_response.json()) + except ValueError: + response_str = ""
