+## Troubleshooting
+
+
+If you got an issue like :
+
+```
+ events.js:292
+     throw er; // Unhandled 'error' event
+     ^
+
+ Error: ENOENT: no such file or directory, open '/tmp/tmp-11UOaQJNu37LGm.tmp.png'
+ Emitted 'error' event on ReadStream instance at:
+     at internal/fs/streams.js:136:12
+     at FSReqCallback.oncomplete (fs.js:156:23) {
+ errno: -2,
+ code: 'ENOENT',
+ syscall: 'open',
+ path: '/tmp/tmp-11UOaQJNu37LGm.tmp.png'
+ }
+ Error running filter mermaid-filter:
+ Filter returned error status 1
+```
+
+To fix it, create a file called `.puppeteer.json` in the directory you run pandoc, that contains
+
+```
+ {
+     "executablePath": "/usr/bin/chromium-browser",
+     "args": ["--no-sandbox"]
+ }
+```
