What I’m trying to do:
Make a server call to an Uplinked function. This is code that has been working for years…
Error message is:
AnvilWrappedError: No module named 'anvil.tables.v2'
at <frozen importlib._bootstrap>, line 965
called from <frozen importlib._bootstrap>, line 983

called from sm_request_report_pipelined, line 62
Further lines of the traceback are from my code. This error is occurring with Firefox, Chrome, and Edge. Module sm_request_report_pipelined hasn’t changed since early May, and did not experience this error last week.
Given the top lines of the traceback, I am at a loss as to how I could have caused such an error. If it is my doing, I’d love to know how, so that I can prevent it in the future!
I am very glad to be getting solid tracebacks today, in a timely manner. This was not always the case, and I very much appreciate having them.
What I’ve tried and what’s not working:
I searched for references to “anvil.tables.v2” in this forum, in the hope of a clue, but nothing turned up.
Code Sample:
# web-service imports
import anvil.users
import anvil.tables as tables
from anvil.tables import app_tables
import anvil.server
...
def request_a_report_from_home_office_pipelined(log_entry_id, request_as_text):
"""...pipelined means, it does NOT wait for the report to be completed.
The return value is an error message; or None, if all went well.
"""
remote_listener_fn_name = 'enqueue_job'
try:
result = anvil.server.call(remote_listener_fn_name,
log_entry_id,
request_as_text
)
except anvil.server.UplinkDisconnectedError:
return "ERROR: Remote listener function has disconnected"
except anvil.server.NoServerFunctionError:
return "ERROR: Remote listener function is not available."
except anvil.server.TimeoutError:
return "ERROR: Remote listener did not respond in time."
else:
return None # no exception occurred
