Exception: Value passed to "phutil_string_cast()" is an array in PhabricatorApplicationSearchEngine.php
Closed, InvalidPublic


Upstreaming this from our server logs (Phorge at 52be52d429ce); I checked that we have no offset of line numbers in downstream - there is not.

I'm quite puzzled that $query_key can be an array here. Looks like some Conduit API calls might allow passing that?

This code area was recently changed. In this code was changed to if ($query_key === null || !strlen($query_key)) instead of Phorge's D25204 $is_empty_query_key = phutil_string_cast($query_key) === '' approach.

Event Timeline

Without a reproduction, this is speculative.

Note that the upstream solution from Phabricator does not fix your problem, since


Warning: strlen() expects parameter 1 to be string, array given in /home/user/scripts/code.php on line 2

This is causing a warning at least since PHP 4

It could also be some bots sending you fuzzy input. Consider to mark as invalid, until a real human being elevates this as a problem affecting some workflows.

Decreasing just a bit the priority since we are a bit confused about how to proceed but feel free to change

Makes sense; let's close for now. (I need to get used to Conduit throwing exceptions into our server log for random broken input. I do not like that Conduit behavior.)
