Issue with Global Variables Not Passing in Query Parameters for Custom Function Tool

Support Help
1

I’m using the function tool to call an external API, but I’m facing an issue when trying to pass global variables into query parameters. Here’s what I’ve done:

  1. I’m extracting variables like name and birthdate from the conversation using the “Extract Dynamic Variable” function.

  2. I then pass these values into the API Endpoint URL using query parameters, such as https://hapi.fhir.org/baseR4/Patient?name={name}&birthdate={birthdate}.

  3. However, when I run the tool, the correct arguments are retrieved, but the variables are not passed properly into the query parameters.

The function returns the error HAPI-1940: Invalid date/time/quantity format: "{birthdate}", meaning the global variables are not being interpolated in the URL as expected.

Question:

  • Is there a specific step or configuration I might be missing to ensure the global variables are correctly passed in the query parameters?

  • How can I ensure that the variables extracted in the conversation are properly inserted into the API endpoint during the function call?

Any guidance on this would be appreciated. Thanks!

Hello @Nofal_butt

You need to use the variables between double {{}}, not single {}

Try this if you still have an issue, you can share the call id and I will take a look
