Unsupported Features Reference

Some n8n nodes and features don't work on indie.money due to platform constraints. This list explains why and provides alternatives.

Database Nodes

Not Supported: Postgres, MySQL, Redis, MongoDB, Microsoft SQL, SQLite

Reason: Database clients require direct socket connections unavailable on the platform.

Alternatives:

  • Use HTTP-based APIs or services
  • Consider serverless database alternatives

See: Known Limitations


LangChain Vector Stores & Embeddings

Supported: Supabase, Pinecone, Qdrant vector stores; OpenAI, Ollama, Google Gemini, and Azure OpenAI embeddings

Not Supported: In-Memory, Weaviate, Chroma, Milvus, Zep vector stores; Cohere, HuggingFace, Mistral embeddings

Reason: Unsupported nodes require connection protocols or infrastructure not available on the platform.

Alternatives:

  • Use Supabase, Pinecone, or Qdrant for vector storage
  • Use Embeddings OpenAI or Embeddings Ollama for text embeddings
  • Call other embedding APIs via HTTP Request node

LangChain External Memory

Not Supported: Motorhead, Postgres, Redis, Xata, Zep, MongoDB-backed memory

Reason: Requires TCP/database connections.

Alternative: Memory Buffer Window for in-conversation context.


Streaming Responses

Not Supported: Real-time streaming from LLMs or external APIs

Reason: Server-Sent Events (SSE) streaming is limited on the platform.

Workaround: Poll for results or use batch responses.


File System Access

Not Supported: Reading/writing local files

Reason: The platform runs in a sandboxed environment without file system access.

Alternative: Use external object storage services (e.g., S3-compatible APIs via HTTP Request).


TCP Connections

Not Supported: Direct socket connections

Reason: Direct socket connections are not available on the platform.

Alternatives: Use HTTP-based APIs or proxy services.


Form Trigger and sendAndWait

Not Supported: Form trigger node and sendAndWait operations on communication nodes (Slack, Teams, Discord, Telegram, etc.)

Reason: These require a hosted form UI and webhook resume mechanism not available on the platform.

Alternatives:

  • Use Webhook + Wait nodes for human-in-the-loop workflows
  • Use the Respond to Webhook node to return data and wait for an external callback

Long-Running Operations

Limitation: 30-second CPU time limit and 5-minute wall-clock timeout

Reason: The execution engine enforces a 30-second CPU time limit (network I/O wait does not count) and a 5-minute total wall-clock timeout (including I/O wait). Most workflows are bounded by API response times (I/O), not CPU.

Workaround: Split CPU-intensive operations into multiple agent executions using triggers.


Integration Nodes with Incompatible Authentication

Not Supported: PostHog, ERPNext

Reason: These nodes use authentication patterns that are incompatible with indie.money's Secure Vault credential proxy:

NodeAuth PatternWhy It's Incompatible
PostHogBody-based API keyInjects the API key into the request body. Secure Vault only injects credentials via headers or query parameters.
ERPNextTwo-secret token (key + secret)Requires both an API key and an API secret. Secure Vault models a single secret per credential and cannot supply the second value.

Alternatives:

  • Use the HTTP Request node with manual authentication for these services

Analytics & Metadata Nodes

Not Supported: Track Time Saved (n8n-nodes-base.timeSaved), Execution Data (n8n-nodes-base.executionData)

Reason: These nodes feed n8n's internal insights and execution-search dashboards, which don't exist on indie.money. Track Time Saved is permanently unsupported β€” the concept is not applicable to serverless execution. Execution Data is blocked at activation with no replacement. Neither is a temporary gap.

Alternative: None for time-tracking. To persist your own custom metadata, use a Data Table.


Unsupported n8n Triggers

Not Supported:

  • Workflow Trigger (n8n-nodes-base.workflowTrigger) β€” Deprecated by n8n. Fired on workflow lifecycle events (activated, updated) that don't apply to indie.money's serverless model.

Alternatives:

  • Use Execute Workflow Trigger for sub-workflow calls
  • Use Schedule Trigger or Webhook for event-driven workflows
  • Use Stop and Error + IF nodes for in-agent error handling
