Troubleshooting
A running log of real problems hit during development (or day-to-day life) and how they got fixed. The point isn't documentation for its own sake — it's that unsolved-then-solved issues have a habit of coming back to haunt you later. Writing the fix down once means next time it's a search away, not a re-investigation.
This is different from the topic-based Knowledge Base sections: those are "here's how X works," this is "here's a specific problem I hit and exactly what fixed it."
When to Add an Entry
Add an entry any time you spend more than a few minutes chasing down a bug, a confusing error message, or a broken environment/tool — especially if the fix wasn't obvious from the error itself. If you had to search, experiment, or dig into logs to find the answer, it's worth capturing.
How to Add One
-
Create a new file directly under
docs/troubleshooting/, named for the problem (e.g.flask-cli-command-not-found.md,poetry-lock-conflict.md). -
Copy the structure below (Problem, Environment, Root Cause, Fix, Prevention).
-
Add tags (at minimum the relevant technology, plus
troubleshooting). -
Link the new entry from the Entries list below.
See Contributing for the general file/naming conventions shared across the whole knowledge base.

# Short, Specific Problem Title
One sentence describing what went wrong, in plain language — this is what you'll be
scanning for six months from now.
## Environment
- Tool/library + version:
- OS / runtime:
- Any other relevant context (framework version, deployment target, etc.):
## Problem
What happened. Include the exact error message or symptom, verbatim — this is often what
you'll be searching for later.
```text
Paste the exact error/traceback here.
```
## Root Cause
Why it actually happened, not just what made the symptom go away. If you never fully
figured out the root cause, say so explicitly rather than skipping this section.
## Fix
The concrete steps or code that resolved it.
```bash
# commands, if applicable
```
## Prevention
How to avoid hitting this again — a config change, a habit, a check to add to a checklist,
or just "now I know to look here first."
