Troubleshooting

Use this page to help users correct packaging and handoff problems before they consume a run.

Missing project directory​

If the runner or validator reports an error similar to:

Project directory not found: <input-root>/<project_id>

check the following first:

  • config.projectId matches the staged folder name exactly
  • The files were copied into <input-root>/<project_id>/01_sources/
  • The files were not copied one level too high or too low

Quick check:

ls -la /data/input/<project_id>/01_sources/

Missing required files​

The minimum valid package needs:

  • sources.json
  • portfolio_selected.csv

If either file is missing, or if sources.json points to a missing file, treat the package as blocked until the file set is repaired.

Invalid portfolio file​

If portfolio_selected.csv is present but the package still fails validation, inspect the header row. One of these columns must exist:

  • smiles
  • canonical_smiles

If neither is present, the validator should block the submission because the current runner contract will not be able to resolve the molecular input correctly.

Optional files are missing​

Missing optional files such as assays.csv, compounds.csv, targets.csv, or structure files do not always require a hard stop. The safer behavior is:

  • Show a warning
  • Explain which downstream analyses may have reduced coverage
  • Let the user decide whether the run is still useful

Handoff succeeds but runtime later fails​

If the package validated in PreFlight UI but the job still fails later, compare the staged inputs with the effective runtime settings:

  • config.projectId
  • config.runMode
  • Storage mount path or bucket path
  • File permissions on the staged directory

This is usually a deployment mismatch rather than a schema mismatch.

Permission issues on staged PVC data​

If helper pods or the runner cannot read the staged files on a PVC, fix the directory permissions before rerunning:

kubectl -n "${NAMESPACE}" exec gbx-input-writer -- \
  /bin/sh -lc "chmod -R a+rwX /data/input/${PROJECT_ID} || true"

When to escalate​

Escalate the submission for operator review when:

  • The package structure is correct but the manifest semantics are unclear
  • Multiple candidate identifiers conflict
  • Referenced structure files cannot be tied confidently to the selected portfolio
  • The user is unsure whether a missing optional file is acceptable for the chosen workflow
