The anxious ghost of Tony Blair strikes again
Tony Blair is the living embodiment of what happens when political office becomes a down payment on future plunder. Ejected in 2007 by his own MPs as a massive liability, he bequeathed Britain a wild casino economy primed for the 2008 crash. And when the Brit…

Fusion - nested string arrays. How to use the explode command
I have imported my dataset created by Contour into Fusion. Whilst it has created 9 columns for the data, it has only produced a single row. I believe the term is nested. I have seen various commands online i.e. explode followed by other commands. But this doesn’t seem to be working or it may in fact be me applying this incorrectly. I can drag the columns down which then populates the rows but would prefer all the rows appearing automatically as the data changes. Grateful for step by step commands, actions to follow to accomplish this. 1 post - 1 participant Read full topic
Workshop - Button to appear to show when a filter has been applied
I am trying to create a button that only appears when a filter has been applied by the end user. This is to ensure the user is aware they are not seeing all the data. My object set always has a value but my filter output value is either ‘no filters’ or the values of my filters that I have applied. I see there is a conditional visibility on the button widget but I am struggling on how to setup the boolean variables to do this and/or other variables that might be needed to accomplish this. I am most probably looking at this at the wrong angle. So any help would be much appreciated. 3 posts - 3 participants Read full topic
Embedding large third-party React SDKs
I’m building a Foundry React app with Ontology SDK integration and trying to connect Box.com as a governed content layer for Foundry records. I successfully: create Box folders automatically from Foundry store Box folder IDs/URLs on objects My issue is the UI layer. I tried embedding Box Content Explorer / Box UI Elements in both: custom widgets hosted React apps but ran into CSP restrictions and major dependency/runtime issues with Box UI Elements in Foundry’s Vite/esbuild environment. Question: What is the recommended Foundry-native pattern for integrating external content systems like Box or SharePoint into React applications? Should the UI generally be: native Foundry React components + external APIs instead of embedding third-party UI SDKs? Has anyone successfully embedded large third-party React SDKs in hosted Foundry apps? 1 post - 1 participant Read full topic

First build after Marketplace installation fails — Data Connection source returns empty URL
After installing a Marketplace product, the first build of a transform that uses an external data connection fails with: MissingSchema: Invalid URL ‘’: No scheme supplied. Perhaps you meant https://? The transform fetches data from a REST API using rest_api_source.get_https_connection().url , but on the first build the URL resolves to an empty string. The subsequent retry (triggered minutes later) succeeds. Logs: [GLEIF][spark-transform] LEI 20260524: fetching from [GLEIF][spark-transform] Downloading ERROR: LEI 20260524 UNEXPECTED ERROR [MissingSchema]: Invalid URL '': No scheme supplied. Expected behavior: The data connection source should be available on first build after installation. Actual behavior: First build gets an empty URL from the source. Retry succeeds, suggesting a timing/initialization issue with the data connection during installation. Question: Is there a known delay between product installation and data connection source availability? I
Adding Foundry support for FastAPI web app with SQL backend
Hi there We’re a startup building an agent optimization platform. One of our clients is using Palantir Foundry to store their data and they have asked us to integrate our platform into Palantir Foundry. Essentially, our platform is a FastAPI server connected to a SQL DB where it reads/writes information (sometimes on the hot path). Our schema backend implements ~100 functions that, under the hood, call a bunch of SQL queries. We also have maximum inner product search over vectors (we use extensions like pgvector in Postgres). For integration into Foundry, I was thinking about representing our DB as an Ontology. Couple of questions: Does this make sense? Is the latency and parallelism going to be okay? Is there a better way to do this than creating an ontology? How would you handle maintainability? Our schema still changes, and I kind of want to avoid having to manually tweak the ontology every time we change it. Is here someone who would like to help with that? Sort of
Accessing Foundry Value Types in Typescript V2 Repositories
Hello all, Is there any way for me to directly or indirectly reference the custom types I’ve made in foundry through the SDK in my typescript v2 repository? If not does anyone know if this feature has been discussed in a future roadmap? Thank you, Chase 1 post - 1 participant Read full topic

Add Image to Image Media Set Through Workshop Button Widget
I have a Image Media Set that feeds into Pipeline builder. The pipeline pulls meta data from the image along with builds out some other static columns and produces a dataset. This part works great. But I want to be able to add images to the Media Set through Workshop. I figured out that I can do this through the ‘media upload’ widget, but it wants a function-backed action output, which I do not need. It says that I should “ For single item uploads that do not need to trigger a function-backed Action, use the Button Group to open an Action form to perform the upload .” But I cannot figure out how to do this through the Button Group widget. Any advice on how to do this? 2 posts - 2 participants Read full topic

In Workshop map widget, enable the 'Infer min/max' option when coloring by expression
When setting up a map using a Choropleth display, if you color by aggregation there is an option to ‘infer the min/max’ on the color spectrum. However, this option does not exist when coloring by an expression, which I need to use to aggregate across multiple properties. This means the display isn’t dynamic (e.g. if the underlying data is filtered to small range). 1 post - 1 participant Read full topic
