Hi, thanks for the report. Can you provide more details? In particular:

• Version of GIMP
• Procedures and constraints used (in the Export Layers dialog, choose Settings → Show More Settings to display them)
• Is there any other error/warning message displayed in GIMP, such as a popup or a message in the bottom panel in GIMP?
• Does the error always occur for one particular layer only?
• Does the error always occur for the PNG format only?

I'm getting this same issue.

• GIMP version 2.10.38
• use layer size, layers, visible; file name [layer name]_sans
• no other warnings anywhere that I can see
• appears to always pick the first layer
• I was trying to convert to TGA
  I thought it might possibly be that I was using backticks in the layer names, but removing those didn't change anything. Ditto for my layers all being text layers.

@Kestrelguy If it's OK with you, can you send me the XCF file containing the layers that cause the export to fail?

Also, in the meantime, does this happen if you export the entire image via Export As...?

here's the file.
bizarrely, when I try to export it, GIMP gives me an error about not recognizing the file type… but that wasn't happening the day I got the error in this thread. (in fact, I tried to use this specifically because I'd started exporting layers individually and then decided it was too tedious.)

[kamilburda]

Thanks for the file. I tried exporting the layers to PNG and TGA and it worked on my end (Windows 11, GIMP 2.10.38, Export Layers 4.1).

When you hit Export, do you see the dialog for adjusting TGA format options? If you see the error message instead, this may very well be a problem within Export Layers.

However, if the error message says "execution error", I have difficulties identifying the problem. The thing is, the error messages are spawned by GIMP or the file format plug-ins (not Export Layers) and I am relying on the description to help identify the problem.

In case you get the "unknown file type" message, I can think of two causes:

• In Export As..., you need to type the file extension explicitly in the Name field.
• If you have anti-malware software installed, it may have flagged some file format plug-ins as malware (which I find highly unlikely, though). If you go to Help -> Procedure Browser and type file-png-save in the Search field, it should yield a result. Ditto with file-tga-save. If not, then you may have to reinstall GIMP or try to restore the file(s) that your anti-malware quarantined.

[Kestrelguy]

okay, so as it turns out, my problem last night was that I'd removed the path to the plugins that managed all the file types. whoops.
having fixed that problem… the layer export plugin works fine??
I have no clue what happened, because when I tried a couple weeks ago, I got the giant block of code (multiple times in a row) in the original post, but I didn't get it at all last night or tonight. so that seems to have gone away on its own?
sorry for wasting your time.

[kamilburda]

No problem! Glad you got it working. ☺️

Export Layers depends on the file format plug-ins, so if those work properly, then the export should work fine.
