If I attempt to preview a transform that has a REST API source I am getting the following error:

Traceback (most recent call last):

After merging all open PRs then upgrading the repo this went away. I am not a fan of breaking changes. I know I should keep my repos up to date, but breaking functionality is not cool. I really wish the team would find better ways to ensure backward compatibility as there is a massive cost associated with random breaking changes that just show up in platform. At my work we spent the last day trying to figure this out, and it affected multiple developers and repos. You should be able to progressively enhance the repository based on the dependency versions using a builder pattern or similar method without breaking existing repos.

I am experiencing the same issue but no open PRs…
Any suggestion?

You need to click top right on the “upgrade repository” so that an upgrade PR will be opened.

You can then merge this upgrade PR.

Well noted for the frustration this may cause. Thanks for sharing.

I am experiencing the same error message when I set a breakpoint and preview & debug. I have no open PRs and all branches in the repo have been upgraded and are up to date.
Any thoughts?

Hello,

I’m thinking that this is affecting all repos using the external system decorator, I am experience the same as @chan_ells.

Hey @PaulBurnsAxisData, we have rolled out a fix on most Foundry instances with a couple still in the process of upgrading.

With that being said, if you are still encountering this issue, try the following steps:

  1. Restart your workspace a couple of times to ensure that any new changes are picked up.
  2. Upgrade the transforms-external-systems library in your transforms repository to a version >= 0.709.0, which should resolve the issue.

Rebuilding the workspace worked, thanks!
