How do I prevent Git commit error (An internal error occurred...)?

Question: I used to be able to commit my Datical project using Datical GUI. Now I'm seeing an error when I try to commit my changes.

This happens when I right-click on my project > select Team > select Commit > type my commit message and press the Commit button. I get this error:

I didn't change anything on my side. Since I started seeing this error, I've also performed a clean install of Datical followed up installing drivers. I still get this error.

Looking into metadata.log file, I see this message (notice half way through this message: "Input did not match supplied length. 150 bytes are missing."):

Answer: The solution to this problem is to set core.autocrlf=false.

The way to set this in Datical GUI is go to File > Preferences > Team > Git > Configuration.

If core.autocrlf is set to true, then change its value to false.

If not already set, click New Entry... button and provide these values:

Key: core.autocrlf

Value: false

Then click Apply and click OK. Restart Datical GUI and try committing your project again.
