"Export Config panicked" error when exporting from OCIO maker

[FinnTiger10]

When attempting to export from OCIO Maker the following error is displayed in the log:
ERROR: ERROR: job "Export Config" panicked!

The LUT I'm using was created in LUT Maker. When I estimated the transfer function, LUT Maker was not able to estimate the floor or ceiling, but the created LUT still seems to work fine in DaVinci Resolve.

The issue occurs with any gamut and configuration base, and with both .CUBE type LUTs and .spi1d type LUTs.
I am using Image Tools v0.4.0 on Windows 11.

Thank you for the report!

Can you provide the LUT in question, and the specific settings of the configuration you're trying to generate? That will make this much easier to track down and fix.

(Edit: sorry, read too fast, and somehow missed where you said the specific configuration settings don't matter.)

Hello, please see the following Google Drive links:
.spi1d file - https://drive.google.com/file/d/1lumA2PqYBYkZeCVlD0nPd6CiIZZgj8rr/view?usp=sharing
.CUBE file - https://drive.google.com/file/d/1PkRrqNWub4CKLgHpIn9Qo2jc8Gk_8KKm/view?usp=sharing
(both files should be the same though)
Thanks

Unfortunately I'm unable to reproduce the issue: exporting a config that uses those files works fine for me with 0.4.0.

I'm not running Windows, so it's possible that it's a Windows-specific bug.

Are you sure it's the LUT files that are the issue? Does config export succeed when using other LUT files?

Hello,

I did some experimenting and got it to work! I think the issue is that I was exporting the config files to a folder on OneDrive, as when I tried it on my hard drive everything worked perfectly.

Thank you for your help!
