Octolapse does not take any snapshot but logs an error

[Gerporgl]

If this is a feature request describe it here

Version of Octolapse

Octolapse Version: 0.4.0

Version of OctoPrint

OctoPrint Version: 1.4.0 and 1.4.2

When you ran into the problem, did you have diagnostic logging enabled?

Diagnostic Logging was Enabled: YES (default logging level)

What were you doing when the problem occurred

1. Printing a test cube with octolapse in test mode

What should have happened?

Octolapse should have taken a snapshot instead of showing an error on each layer change (this is my understanding of what octolapse should be able to do)

What happened instead?

There was a red popup in octoprint from octolapse saying "Stabilization Error
An unexpected error was encountered while running the timelapse snapshot procedure."
I tried this initially a couple of weeks ago with Octoprint 1.4.0, then retried today with 1.4.2 but getting the same error message.
I also tried with other Stabilization setups but that did not help.

Operating System running OctoPrint and Octolapse

OS Name: Armbian Focal for Odroid C2
Os Version: Armbian Focal Fossa (20.04) with Linux 5.6.18-meson64

Printer model & used firmware incl. version

Link to the gcode file you were printing when the problem occurred

Link to Gcode File: I don't think it is needed since I tried with many different gcode files, the error seems to be something else entirely.

If you like this project, please support my work by becoming a patron, and consider adding a 'star' to the repository. It takes a lot of time and effort to maintain the project and respond to issues. The cost of test prints, software, cameras, printer parts, etc. can quickly add up, so every bit helps.

I saw this in another issue. Looking into it.

@Gerporgl , can you try installing from the plugin manager using this link in the From Url... box: https://github.com/FormerLurker/Octolapse/archive/88aa71f0fbac306b0d9acf19dff7388a30b29b64.zip

See if that fixes it.

[FormerLurker]

This should be fixed in V0.4.1, which just dropped. Might take a while to show up in the plugin manager. Reopen a new issue if you continue to have problems. Thanks!
