HIOT-159

The file upload to HULFT IoT Manager might fail

Phenomenon

When the user performs either of the following operations, the file upload might fail.

1. Registering the upload module of HULFT IoT Agent
2. Registering the file used for the file distribution

Affected versions

From Ver.1.0.0 to Ver.1.5.0 (phenomenon 1)

From Ver.1.1.0 to Ver.1.5.0 (phenomenon 2)

Version when it was corrected

Ver.2.0.0

Affected module

HULFT IoT Manager

Condition to reproduce

The file upload fails if the Manager's working directory that was created in the temporary directory has been deleted by the OS function that periodically deletes the temporary directory and so on.

Alternative workaround

Restarting HULFT IoT Manager, Manager creates the working directory in the temporary directory, and the file upload will be enabled.

But if the working directory is deleted again, the problem will occur again.

Status description

Manager creates the working directory in the installation destination.

This avoids the unintended deletion of the Manager's working directory.
