1698865182,I_kwDOBm6k_c5lQqAe,2069,[BUG] Cannot insert new data to deployed instance,31861128,open,0,,,1,2023-05-07T02:59:42Z,2023-05-07T03:17:35Z,,NONE,,"## Summary
Recently, I deployed an instance of datasette to Vercel with the following plugins:
- datasette-auth-tokens
- datasette-insert
With the above plugins, I was able to insert new data to local sqlite db. However, when it comes to the deployment on Vercel, things behave differently. I observed some errors from the logs console on Vercel:
```console
File ""/var/task/datasette/database.py"", line 179, in _execute_writes
conn = self.connect(write=True)
File ""/var/task/datasette/database.py"", line 93, in connect
assert not (write and not self.is_mutable)
AssertionError
```
![]()
I think it is a potential bug.
## Reproduce

""$env"": ""INSERT_TOKEN""
},
""actor"": {
""id"": ""repeater""
}
}
],
""param"": ""_auth_token""
}
}
}
```
commands
```bash
# deploy
datasette publish vercel remote.db \
