getLatestsResult gives an ArrayIndexOutOfBoundsException, and sometimes the photonvision frontend is loading without showing anything. #1072

Describe the bug When using the getLatestResult function in java, with the latest vendordep, the following exception appears: ERROR  1  Unhandled exception in Notifier thread: java.lang.ArrayIndexOutOfBoundsException: Index 914 out of bounds for length 914  org.photonvision.common.dataflow.structures.Packet.decodeByte(Packet.java:145)   Error at org.photonvision.common.dataflow.structures.Packet.decodeByte(Packet.java:145): Unhandled exception in Notifier thread: java.lang.ArrayIndexOutOfBoundsException: Index 914 out of bounds for length 914   at org.photonvision.common.dataflow.structures.Packet.decodeByte(Packet.java:145)   at org.photonvision.targeting.PhotonTrackedTarget.decodeList(PhotonTrackedTarget.java:208)   at org.photonvision.targeting.PhotonTrackedTarget.createFromPacket(PhotonTrackedTarget.java:243)   at org.photonvision.targeting.PhotonPipelineResult.createFromPacket(PhotonPipelineResult.java:170)   at org.photonvision.PhotonCamera.getLatestResult(PhotonCamera.java:198) 

Additionally, sometimes, the photonvision client just loads and doesn't show anything with the following problem in the system log: Dec 08 11:37:48 photonvision java[3243]: [2023-12-08 11:37:48] [WebServer - Server] [DEBUG] Handled HTTP request of type GET from endpoint /assets/loading-0f0dc28b.svg for host 10.59.90.221 in 1.005646 ms Dec 08 11:37:48 photonvision java[3243]: [2023-12-08 11:37:48] [WebServer - Server] [DEBUG] Handled HTTP request of type GET from endpoint /assets/logoLarge-7c0b93cf.svg for host 10.59.90.221 in 2.909024 ms Dec 08 11:37:48 photonvision java[3243]: [2023-12-08 11:37:48] [WebServer - Server] [DEBUG] Handled HTTP request of type GET from endpoint /assets/prompt-latin-400-normal-b7be1a25.woff2 for host 10.59.90.221 in 1.534719 ms Dec 08 11:37:48 photonvision java[3243]: [2023-12-08 11:37:48] [WebServer - Server] [DEBUG] Handled HTTP request of type GET from endpoint /assets/materialdesignicons-webfont-c1c004a9.woff2 for host 10.59.90.221 in 1.544052 ms Dec 08 11:37:49 photonvision java[3243]: [2023-12-08 11:37:49] [WebServer - Server] [DEBUG] Handled HTTP request of type GET from endpoint /favicon.ico for host 10.59.90.221 in 2.929731 ms

To Reproduce Steps to reproduce the behavior: Use photonCamera.getLatestResult(); idk why the second problem occurs.

You need to be using the same vendordep version and photonvision version, so I'm not shocked about the array out of bounds. You should have seen a warning earlier in your logs telling you about the version mismatch as well.

Wait, is there a newer version for the vendordep? Vs code didn't show anything

mcm001 commented 8 months ago

Yeah, vscode won't show it but we have a beta vendordep. Replace the version string with the version of photon on your Coproc

I changed the version and a similar issue occurs.

Not able to reproduce with my vendordep version and photon version set to dev-v2024.1.1-beta-3.2-27-g0b98f027
