Also I’m using astarPath.data.DeserializeGraphs(data); to load graph data. Its loads as well and i received logs for that as well. After this in a second/two, the build crashes, with the above logs. Im using Entities 1.3.14

tealtxgr · June 13, 2025, 10:40pm

And this is only after DeserializeGraphs? What version of Unity are you on?

Ritwik_Sinha · June 15, 2025, 3:32am

Yes it was happening after the graph was loaded, didnt receive the message then.

After that i was finding the nearest node point for target destination, and at that point it gave the fatal error.

After this i used aipath.cs, and the error was gone. But i find follower entity to be better, but cannot use it in linux build unfortunately because of the fatal error.

Also im on Unity 2022.3.52f1

Hi

I would try to upgrade to a newer version of unity, as this could very well be a burst/unity bug.

Otherwise, I’d try to see if you get the same crash in a debug build.

Ritwik_Sinha · June 16, 2025, 10:25am

Sure, thanks, just another update its Unity 2022.3.58f1. Please ignore the previous version.

Ritwik_Sinha · June 26, 2025, 2:25am

Please let me know if its fixed, i might nwed some solution soon. Let me know.

aron_granberg · June 26, 2025, 8:41am

I was waiting on an answer from you…

Ritwik_Sinha · June 26, 2025, 8:47am

Ohh okay, sure, will try a debug build and revert soon.

aron_granberg · June 26, 2025, 8:54am

A newer version of Unity and/or your entities package wouldn’t hurt either. This could very well be a unity bug.

Ritwik_Sinha · August 8, 2025, 8:10am

Hi @aron_granberg

So there is a new update, it seems the previous error was not the issue related to this plugin probably.
But now that weve narrowed down, we’ve found the following issue that is coming up in headless liunx dedicated server build.

So im using the following method to find node

I got the following issues

So the above issue comes after i allow the scan in runtime in linux

Previously i was using the cached graph data and loading it on start.
I was getting the following error.

2025-08-07T03:15:58.660Z Mumbai[0ee9eacc] AstarPath is not active or no graphs available or no nearest node found.

For both the scenarios, in editor it works fine.I tried setting the following as well

In above Heuristic was Euclidean, then i tried to none and also reset the thread count to none.
The error remained the same with scan on awake or using cached graph. For all cases i had checked on editor it worked fine in editor.

Please let me know the next steps, what should i try ?

tealtxgr · August 11, 2025, 5:05pm

Hey there, would you be able to try updating Entities? Have you had the chance to check what version you’re on for that package?

Ritwik_Sinha · August 12, 2025, 8:31am

Im on 1.3.14 version which is i think is the latest package as of now.

aron_granberg · August 12, 2025, 8:59am

If you set Heuristic to None, then the first error should not be possible.

I was getting the following error.

2025-08-07T03:15:58.660Z Mumbai[0ee9eacc] AstarPath is not active or no graphs available or no nearest node found.

This happens if you try to query the graph, or issue path requests, before the cached graph has been loaded. Or if you don’t load the cached graph at all.

Ritwik_Sinha · August 12, 2025, 10:21am

Yes i have tried setting Heuristic to None.
Also after i did some changes, where the scan happened and then after that only the AstarPath.active.GetNearest method was called

This is where i was receiving this error may times
Two types of error are there :-

2025-08-09T09:56:17.382Z Mumbai[c43f6173] No nearest node found.

and

2025-08-09T09:36:16.228Z Mumbai[f8b937f8] Path Failed : Computation Time 0.00 ms Searched Nodes 0
2025-08-09T09:36:16.228Z Mumbai[f8b937f8] Error: Couldn’t find a node close to the start point

Even on loading the graph via cache, this error still came.

This is another image sample which shows both the errors received.

Also i added logs to confirm if the scan was truly happening, this is what i get. This confirms that the scan was done.

Additionally, the same setup works fine on editor everytime.

aron_granberg · August 12, 2025, 10:29am

Hi

I note that you get the warning “Some mesh collider meshes could not be included…”.
This warning indicates that it would only have been able to read this mesh data in the unity editor, not in a standalone game. This could very well be the reason.
A list of these meshes will show up in the recast graph inspector as a big warning after you have scanned the graph.
Check it out.

Ritwik_Sinha · August 13, 2025, 11:51am

Hi,

So i’ve removed that warning message by marking those mesh as readable, there were around 17 of them. Now that error message didnt come, and in the linuxbuild, the following message is shown.

That warning message is not there anymore.

The path is still failing most of the time and the node is returned null some times as well

Im sharing the settings screenshot of Astar script

Im doing the scan manually via another script as of now. Although ive tried both scan on awake and cache loading, the error remains the same.

Ritwik_Sinha · August 13, 2025, 2:07pm

I tried creating a build which loaded prescanned graph byte data and the following was achieved. I had added some manual logs.

After that, when the scan was completed, the following was received continously

One difference I noticed was that, “No Nearest node found” was no longer found in these set of logs, which was coming from the following code.

After that i tried the following settings

Im getting the same error as above.

In all cases, it worked fine on the editor. What could be the issue? What should i try next ?

Ritwik_Sinha · August 18, 2025, 8:43am

@aron_granberg @tealtxgr Please suggest the next steps, or is it some other issue ?

tealtxgr · August 18, 2025, 6:56pm

I tagged Aron on this for a follow-up. Appreciate the patience
