OpenAI node common issues#

Here are some common errors and issues with the OpenAI node and steps to resolve or troubleshoot them.

The service is receiving too many requests from you#

This error displays when you've exceeded OpenAI's rate limits.

There are two ways to work around this issue:

  1. Split your data up into smaller chunks using the Loop Over Items node and add a Wait node at the end for a time amount that will help. Copy the code below and paste it into a workflow to use as a template.

  2. Use the HTTP Request node with the built-in batch-limit option against the OpenAI API instead of using the OpenAI node.

Bad request - please check your parameters#

This error displays when the request errored but the OpenAI node wasn't able to interpret the error message from OpenAI.

To begin troubleshooting, try running the same operation using the HTTP Request node, which should provide a more detailed error message.

Referenced node is unexecuted#

This error displays when a previous node in the workflow hasn't executed and isn't providing output that this node needs as input.

The full text of this error will tell you the exact node that isn't executing in this format: 

1
An expression references the node '<node-name>', but it hasn’t been executed yet. Either change the expression, or re-wire your workflow to make sure that node executes first.

To begin troubleshooting, test the workflow up to the named node.

For nodes that call JavaScript or other custom code, determine if a node has executed before trying to use the value by calling:

1
$("<node-name>").isExecuted
