The single most useful thing you can give us is when it happened. Our engineers find the cause by looking at server activity around that moment. A timestamp turns a guess into a five-minute fix.
If you already described the problem in chat, it is filed. Missing an order number or screenshot does not mean you still need to send a ticket. Share what you have. We will ask if we need more.
Always helpful
Roughly what time it happened (even "about 10 minutes ago" works)
A screenshot of the error — the whole window, not a crop
What you were trying to do in plain words
The order, job, or item you were working on, if you have it
Not needed
Don't try to diagnose it for us, and don't retype error text. A screenshot is better than a transcription. Don't paste a request template unless we ask. If you were mid-way through something, tell us where you got to and whether you've tried again since.
If you're chatting from inside the tool
Most of this is captured automatically. Just describe what went wrong. That is the ticket.
