Work order submit Problem

Gives a message when i want to submit work order.

Help me to solve this problem


May we know the operating/hosting environment, cpu and memory?

Dear Mr. Smino,
I do not understand. please write details how to solve this kind of problem.

i am using Virtual-box, OS Ubuntu 22.04 LTS, Processor: 4 core, RAM 8GB.


If virtualbox has dedicated 4 cores and 8G ram to the ERPNext machine, there should be enough resources to run it. Do other forms submit without error? Are there any customizations to the Work Order form?

No customization. We working at the default system
