Error saving project

aftermisak

After posing all bone fine, I try to save project and I press command+s. Then I get a error message dialog:
the dialog title is "Error saving project", the error message is "An error occurred while saving the project",
There has no more information for this error. How can I do?

Have you tried going into Spine>Settings... (F12), going to the Log item and clicking Open?
That opens the spine.log file.
Sometimes, when errors don't show anything in the window, it gets written to the spine.log file.

Is this the first time you saved the project since you created it, or did it successfully save previously?

It's not the first time I saved the project since I created it,
It did successfully save previously. I just did some normal operation,
then save.
here is the log msg when I saving:

Can you include the Spine version?

Nate

Please post the entire spine.log file.

Hi, I had this same issue and I found that it was related to saving a very large selection set. About 40 slots with an average of 3 images per slot, and translate / scale / rotate / sheer and constraints and etc. Basically saved a selection for all things that are possible to key.

My solution for programming purposes is to key every single aspect of the dope sheet on the first and last frames of every animation. Therefore, I made a selection set so I could easily select slots, attachments, bones, etc whether they are on or off(thats the most important part)

Anyway, when I went to save it wouldn't let me, it would give me "An error occurred while saving the project"

I was able to fix this problem after I saved over the selection set with a much smaller amount of things selected (like 3 bones only) After I did that it allowed me to save again.

I'm guessing it was just too much data to save.

I don't know if this is related to your issue but this was my issue and how I solved it.

Hello, I'm aware this is an old thread but I'm having problems saving my file because of a similar error. I've never had this error before, and I've saved this file many times before.
Spine version: 4.0.64, Launcher 4.1.03
Error message: "Error Saving Project: An error occurred while saving the project"
I'm assuming the file is too big or something, but I already stripped out a lot of animations, cleaned up the ones still in there and deleted a lot of unused references and skins... and I still get the same error. Anyway, now I'm stuck wondering if I should just cut my losses and quit and try and cautiously start my work today again from scratch...

Log says this repeatedly: "ERROR: Unable to save automatic backup project file: {location} Index 1477837 out of bounds for length 1048576"

(I can't post the full log because it exceeds the max amount of characters, but here is some of it)

The size of stored selections won't cause the inability to save. It is caused by a bug in Spine. When saving, Spine does many checks to ensure the project is in a valid state. When you can't save, it means something about the project is incorrect in a way that Spine can't fix. Usually the project has a reference to something that is no longer in the project. If you can figure out the steps between opening the project and not being able to save, we would LOVE to fix it!

You can attach the log to your post as a file or email it: contact@esotericsoftware.com

However, it's unlikely we can do much unless we know what steps to take so we can see the same problem. Are you able to make it happen every time?

Nate Hi! it happens to me always when I save a selection set in the attachment list located in images folder (setup mode). The solution for me was easy, don't storage selection from the images' folder. Doesn't matter how many images I have storaged in the selection set, with only one is enough to crash. I hope it helps to community.

Hi Nate,
Unfortunately, I did not save the log as a file, I didn't know that I could do that! And now it is overwritten. I haven't had that many issues with Spine in 7 years of using it, so this is a learning experience for me.
Since reporting the problem, I opened a fresh file, lost some work, and have not had the same problem since.
If it crops up again, I'll email the full log.
Thanks for getting back and explaining!
Slava

Nate

You can find the log file here. However, for this problem the log file is unlikely to help. We need to know what actions were taken between when the project file was opened or last saved and when the project could not be saved. Some action or combination of action caused the project file to not be able to save. We need to know those actions so we can reproduce the problem, only then will we be able to fix it. As you can imagine, it can be difficult to determine which actions are problematic. Eventually we'll nail it down!

Nate

@Selmi3D I gave it a try, but images under the Images node aren't saved to my selection group. I select an image, ctrl+1 (the selection group is note stored), and afterward I can still save. Am I taking the right steps? Are you using the latest 4.1? I also tried including an image file along with a bone/attachment/etc, in that case only the bone/attachment/etc is stored in the selection group and I can still save.

Selmi3D

Hi Nate! Sorry, I forgot to mention that the spine version where I got the issue is 3.8.99
In the last spine version, this issue doesn't happen.
Cheers!

Nate

I see, thanks. That means we've fixed it since then.

Hi there! 🙂
If this problem is still present for you (who reading this topic) - I wanna to point on my solution.

I have same symptoms: a big project (1 skeleton, 3 characters inside it, lot of a layout things (background, properties e.t.c.), tons of TC, IK e.t.c.) and yes - once upon a time my project begins to fail savings. Log file says:

or just says:

ERROR: Error saving project:
java.lang.OutOfMemoryError: Java heap space

Then, sometimes it saves with no problem.

So, after hour of researches AND Nate's point of view /* that if the problem with saving of project - smart (!) Spine don't want to save because of non-good state of something in the project*/, I've found problem! 🙂

The problem is: I have tons of animations inside the project: over 100 (versioning of worlkflow). And on some step I deleted some slots, that was used in beginning steps of my project, but not used in the next steps (so I deleted this slots). But the animation with this deleted slots was still presented on my animations branch of tree. And, as I decided, when saving the project - Spine had do something with this old version animations and get the error with this DELETED slots. All I done - I deleted all previous animations (as I don't remember in what version of animations I used this deleted slots - I've deleted all before last=current animation) and leave only current version of animation. So - my project have no problem with saving, also it began to save RAPIDLY (before deleting of all previous animations it was SLOOOW).

Thanks Esoterics for Spine - it awesome! 🙂
