The method looks like:
def _fail_workflow(self, final_context, msg):
if states.is_paused_or_completed(self.wf_ex.state):
return
output_on_error = {}
try:
output_on_error = data_flow.evaluate_workflow_output(
self.wf_ex,
self.wf_spec.get_output_on_error(),
final_context
)
except exc.MistralException as e:
msg = (
"Failed to evaluate expression in output-on-error! "
"(output-on-error: '%s', exception: '%s' Cause: '%s'"
% (self.wf_spec.get_output_on_error(), e, msg)
)
LOG.error(msg)
self.set_state(states.ERROR, state_info=msg)
# When we set an ERROR state we should safely set output value getting
# w/o exceptions due to field size limitations.
msg = utils.cut_by_kb(
msg,
cfg.CONF.engine.execution_field_size_limit_kb
)
self.wf_ex.output = merge_dicts({'result': msg}, output_on_error)
if self.wf_ex.task_execution_id:
self._schedule_send_result_to_parent_workflow()
So, we first utils.cut_by_kb() for "msg" but then, essentially, add 'output_on_error' to it so the resulting size of 'output' may be greater than cfg.CONF.engine.execution_field_size_limit_kb |
The method looks like (with the beginning omitted):
def _fail_workflow(self, final_context, msg):
....
# When we set an ERROR state we should safely set output value getting
# w/o exceptions due to field size limitations.
msg = utils.cut_by_kb(
msg,

self.wf_ex.output = merge_dicts({'result': msg}, output_on_error)

So, we first use utils.cut_by_kb() for "msg" but then, essentially, add 'output_on_error' to it so the resulting size of 'output' may be greater than cfg.CONF.engine.execution_field_size_limit_kb |
