Error message

Error occurred while performing this command, see previous stderr output.

What it means

Identical summary AbortException (CLI_LISTPARAM_SUMMARY_ERROR_TEXT) but from the `online-node` CLI command. Fires after the loop when multiple nodes were requested and at least one failed; per-node errors were already written to stderr.

Solutions

Inspect the preceding per-node stderr lines for the failing agent.
Drop the bad node from the list and re-run.
Pre-filter the list against getComputers().

Defensive patterns

Strategy: validation

Validate before calling

Set<String> known = Jenkins.get().getComputers().stream()
    .map(Computer::getName).collect(Collectors.toSet());
List<String> valid = nodes.stream().filter(known::contains).toList();

Try / catch

try { cli.execute(args); } catch (AbortException e) { /* partial: check per-node stderr */ }

Prevention

Filter node lists before bulk online operations.
Log per-node results so the summary is diagnosable.

When it happens

Trigger: `online-node a b c` where at least one node does not exist or cliOnline fails.

Common situations: Bulk online operations over an inventory list that includes deleted/offline agents.
