settings.environment.validation_duplicate

settings.environment.validation_duplicate

Error message

t("settings.environment.validation_duplicate")

What it means

When adding an environment variable, the mutation checks the cached env items (React Query cache for environmentUserEnvQueryKey) for a duplicate key and throws the localized "settings.environment.validation_duplicate" error if one already exists, preventing a conflicting upsert in "add" mode.

Solutions

1. Use edit/update mode for the existing entry instead of add
2. Pick a unique key name not present in the list
3. Refresh the environment variable list so the cache reflects current server state, then retry

Example fix

// before
mode: "add", key: "DEBUG"
// after (key exists)
mode: "edit", key: "DEBUG", value: newValue

const items = queryClient.getQueryData<{ items: EnvironmentVariableItem[] }>(
  environmentUserEnvQueryKey(runtimeKey),
)?.items ?? [];
if (mode === "add" && items.some(i => i.key === key.trim())) {
  showDuplicateError();
  return;
}
modifyAsync(draft);

try {
  modifyAsync(draft);
} catch (e) {
  if (e.message.includes("validation_duplicate")) highlightExistingRow(draft.key);
  else throw e;
}

When it happens

Trigger: modifyAsync with mode === "add" and a key that already exists in the current environment variable list for this runtime.

Common situations: Trying to add a variable like "PATH" or "NODE_ENV" that already exists; stale list vs. cache mismatch confusion; re-submitting a form after a previous successful add.
