We have noticed a bug in how rootDir that cost us ~$200 in August (I didn’t look at the previous months, but likely in the same range).
The docs say in https:// render .com/docs/preview-environments#root-directory-and-build-filters
If you define the Root Directory or specify Build Filters for each service in your Blueprint Spec, Render will only create a preview environment if the files changed in a pull request match the Root Directory or Build Filter paths for at least one service.
But in practice, we have 3 services that systematically build, even when there are no changes to any of the rootDir folders. For example, https github com/mui/mui-private/pull/1124 triggers https:// dashboard .render.com/blueprint/exs-d2tfk5ggjchc7398kdu0 for no reason.
Can Render fix the build trigger logic? Thanks
