Some parameters of my custom node are of type “options” and I use a http request to fetch the options shown in the UI. In order to make the http request I need to get node’s credentials.
In the custom node credential form, I’m using an expression to get data from previous node and populate the form as the picture bellow:
However I get an error when using the custom node’s helper method this.getCredentials(…).
ExpressionError: No data found for item-index: "0"
The error doesn’t occurs when I fill the credentials form with fixed data rather than expressions.
The workflow is simple like that:
Any ideias why this error occurs?
