Customize and extend the power of Alteryx with SDKs, APIs, custom tools, and more.
Heja,
I feel like I'm on the final stretch to have my Python plugin work properly. It's working in the Designer as well as on the server now -- at least considering the outputs.
When running a workflow containing my Python tool, which has only one input, I receive the following output from the server:
"There was an unknown error executing the application. The engine reported status Error."
When I check the logs on the server, everything looks fine. When running the workflow on the server through AlteryxEngineCmd.exe, the output and log are also fine without any errors.
Anyone any idea how this happens?
I checked whether I didn't close any connections but I have everything in place, I think. Since I don't have any outputs, there isn't any .close() to the outgoing connections.
class AyxPlugin:
def __init__(self, n_tool_id: int, alteryx_engine: object, output_anchor_mgr: object):
self.n_tool_id = n_tool_id
self.alteryx_engine = alteryx_engine
# ...
def pi_init(self, str_xml: str):
xml = Et.fromstring(str_xml)
# ...
def pi_add_incoming_connection(self, str_type: str, str_name: str) -> object:
self.input_anchor = IncomingInterface(parent=self)
return self.input_anchor
def pi_add_outgoing_connection(self, str_name: str) -> bool:
# No outgoing connection
return False
def pi_push_all_records(self, n_record_limit: int) -> bool:
# No outgoing connection
return False
def pi_close(self, b_has_errors: bool):
return
def output_message(self, text: str, messageType = Sdk.EngineMessageType.error):
self.alteryx_engine.output_message(self.n_tool_id, messageType, self.xmsg(text))
@staticmethod
def xmsg(msg_string: str) -> str:
return msg_string
class IncomingInterface:
def __init__(self, parent: AyxPlugin):
# Reference to AyxPlugin
self.ayx_plugin = parent
def ii_init(self, record_info_in: object) -> bool:
return True
def ii_push_record(self, in_record: object) -> bool:
return True
def ii_update_progress(self, d_percent: float):
self.ayx_plugin.alteryx_engine.output_tool_progress(self.ayx_plugin.n_tool_id, d_percent) # Inform the Alteryx engine of the tool's progress.
def ii_close(self):
return
I cannot see any other unhandled Python exceptions or anything the like. And output and log are looking perfectly fine, so I cannot see any problem.
Any idea what might have happened that any workflow containing the tool quits with this error message?
Best
Christopher
