Description
Objective
My goal is to expand a previously completed Meshroom 3D model (from Project A) by automatically adding new photos via the Command-Line Interface (CLI) in a separate project (Project B).
Current Issue
Although the logic for the CLI script is complete, the pipeline consistently fails at the FeatureMatching node with a persistent Invalid regions error. At this point, the problem appears to be not with the pipeline's logic, but with the provided absolute paths to the original data (e.g., typos, file permissions) or a data integrity problem (e.g., a mismatch between the SfM file and the feature set).
Does anyone have ideas or suggestions for what I might be overlooking?

Research direction
Start with the CLI script and the FeatureMatching node configuration described in the issue. Check the provided absolute paths, permissions, the SfM file, and the feature set; done means identifying the cause of the Invalid regions error or documenting the missing information needed to reproduce it.
