Why does sending multiple parameters in my Bubble-n8n API call cause a timeout?

Below is some guidance based on our n8n documentation:

Response Timing and Workflow Duration

When using a GET webhook that waits for the workflow to finish (i.e. the “When Last Node Finishes” response mode), the entire workflow’s processing time factors into the response. This can be problematic if the external service (in your case, Bubble) has a strict timeout setting. Even though your workflow completes successfully, Bubble may still error out because it never received a response within its expected timeframe.

Possible approaches:

• Switch the Webhook Response Mode:
  Consider setting the Webhook node to “Respond Immediately.” This way, the webhook acknowledges the request fast, which may prevent the timeout. You can then process your data asynchronously or implement another mechanism (like a callback) to deliver the result after processing.
  See the Webhook node documentation for details on response options.

• Review Client Timeout Settings:
  If possible, check if Bubble’s API call timeout can be increased. As a client-side timeout issue, a longer timeout setting on Bubble might allow the workflow to complete before the call is considered failed.

The Bubble Node in n8n

The Bubble node in n8n is a dedicated integration meant to simplify interactions with Bubble’s API. However, details about its functionality and configuration can be less comprehensive compared to other nodes. At the moment, the primary documentation covers basic usage patterns but may not include all nuances.

Suggestions for working with the Bubble node:

• Experiment with Simple Calls: Try testing simple data operations first to ensure connectivity and to understand its behavior.
• Review Related Credentials and API Usage: Ensure that any authentication or API key configuration (if required) is set up correctly, similar to how other credentials are used in n8n.
• Ask in the Community: Since documentation can be sparse, the n8n community forum or our GitHub discussions are great places to ask for practical tips and experiences from other users.

Final Thoughts

Longer processing times in your workflow can indeed lead to a timeout on the client side (Bubble) when using a modal response that waits for processing completion. Evaluating adjustments either on the webhook response mode or the client’s timeout settings should help in your integration experiment. For further details on configuring webhook nodes, please refer to the official n8n documentation on Webhook node configuration and response handling.

Hope this helps you in troubleshooting and refining your integration!
