----------------------------------
Summary: Request payload is two endpoints concatenated together
Key: THRIFT-4663
URL: https://issues.apache.org/jira/browse/THRIFT-4663
Project: Thrift
Issue Type: Bug
Components: JavaScript - Library
Affects Versions: 0.11.0
Environment: Python backend
React Javascript frontend
Reporter: David Wire
Originally encountered as a 500 error received from our server.
Investigating the logs on the server came up with this:
{{02:52:33 _elem152 = iprot.readString().decode('utf-8') if sys.version_info[0]
== 2 else iprot.readString()}}
{{02:52:33 File
"/usr/local/lib/python3.6/dist-packages/thrift-0.11.0-py3.6-linux-x86_64.egg/thrift/protocol/TProtocol.py",
line 184, in readString}}
{{02:52:33 return binary_to_str(self.readBinary())}}
{{02:52:33 File
"/usr/local/lib/python3.6/dist-packages/thrift-0.11.0-py3.6-linux-x86_64.egg/thrift/protocol/TBinaryProtocol.py",
line 233, in readBinary}}
{{02:52:33 self._check_string_length(size)}}
{{02:52:33 File

line 47, in _check_string_length}}
{{02:52:33 self._check_length(self.string_length_limit, length)}}
{{02:52:33 File
"/usr/local/lib/python3.6/dist-packages/thrift-0.11.0-py3.6-linux-x86_64.egg/thrift/protocol/TProtocol.py",
line 58, in _check_length}}
{{02:52:33 'Negative length: %d' % length)}}
{{02:52:33 thrift.transport.TTransport.TTransportException: Negative length:
-2147418111}}
It also turned out that this was hitting a different a different processor than
expected.
Upon inspection of the request in the browser client I noticed that the payload
was two processors concatenated together, in this particular case
'get_usersget_episodes'. The failure, I believe, is because it's executing the
get_users processor and trying to turn get_episodes into the parameters for
that processor.
Finally, we realized that we were trying to make get_users request with the
user_ids array (one of the parameters) containing only a null element. [null].
This request is never sent and seems to hang out waiting for the next request
to be sent.
