Lillie Kittredge created NIFI-9048:
--------------------------------------
Summary: PutFile throws NullPointerException writing to a drive
that is not mapped
Key: NIFI-9048
URL: https://issues.apache.org/jira/browse/NIFI-9048
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.11.4
Environment: windows
Reporter: Lillie Kittredge
Repro:
# create a PutFile processor that writes successfully to a directory on a
mapped drive
# change it to write to a nonexistant mapped drive, or remove the user's
permissions to the mapped drive, or run nifi from an elevated prompt so it runs
in to this problem (which is what I ran into in production)

Actual result:

I wasn't able to get a stack trace out of it.
Expected:
An error message that indicates that the drive is not found. When writing to
the root of the bad drive instead of a directory, you get "java.io.IOError:
java.io.IOException: Unable to get working directory of drive 'X'" which is
much better, if we could get the same error when there's a directory that would
be preferable.
