Hi everyone,
I’m running a Streamlit application inside Foundry Workshop, and the app makes a call to a Foundry API endpoint (for example, to retrieve ontology objects or trigger functions).
However, when the call executes, I get the following error:
NameResolutionError(": Failed to resolve 'foundry_host' ([Errno -2] Name or service not known)")
Here’s what I’ve already done:
-
Added the Foundry host URL to the Workspace’s network policy
-
Included the same Foundry host URL in the Streamlit app’s egress network policy
Despite that, the application still cannot resolve the host.
My questions are:
-
Is there another recommended way to reference Ontologies or Foundry APIs from within a Streamlit app without using the explicit Foundry host URL?
-
Is there a built-in way to authenticate or generate a token (for example using the Streamlit runtime or Foundry environment context) instead of manually calling the OAuth/token endpoint?
-
Am I missing any configuration that enables internal API calls from Foundry-hosted Streamlit apps to Foundry itself?
Any advice, best practices, or examples from others who have integrated Foundry APIs in Streamlit would be greatly appreciated.
Thanks in advance!
