Empty profile path

Error message

Empty profile path

What it means

BaseProfile.fromPath is annotated @Contract("null -> fail"): it requires a non-null Path to a profile JSON file. Passing null gives it nothing to read, so it throws IOException('Empty profile path') before attempting to deserialize.

Solutions

1. Check that the profile Path exists and is non-null before calling fromPath
2. Fix the upstream lookup that produced the null Path (wrong profile name or missing profiles directory)
3. Catch IOException around fromPath if null paths are legitimately possible in your flow

Example fix

// before
BaseProfile profile = BaseProfile.fromPath(lookupProfile(name));
// after
Path path = lookupProfile(name);
if (path == null) {
    throw new FileNotFoundException("Profile not found: " + name);
}
BaseProfile profile = BaseProfile.fromPath(path);

if (profilePath == null || !Files.exists(profilePath)) {
    throw new FileNotFoundException("Profile not found: " + profilePath);
}

@Nullable Path resolveProfile(String name) {
    Path p = profilesDir.resolve(name + PMF_EXT);
    return Files.exists(p) ? p : null;
}
// caller: only call fromPath when resolveProfile != null

try {
    BaseProfile profile = BaseProfile.fromPath(path);
} catch (IOException | JSONException e) {
    showError("Cannot load profile: " + e.getMessage());
}

When it happens

Trigger: Calling BaseProfile.fromPath(null), typically when a profile file path lookup failed upstream and the null result was passed through unguarded.

Common situations: Profile name typo causing a directory-listing lookup to return null; calling the API before the profiles directory exists; migrating code that previously used names instead of Path objects.
