# Unable to complete task

**Solution:**

Please note that the task was neither deleted nor affected by any sync issues.

Upon completion, the form contained a field with the value:
 `|| Did not answered call, whatsapp sent||nc`

The segment `"nc"` following the `||` is being interpreted as a command (`netcat`), which triggers our firewall and blocks the task completion.

To avoid such issues, it is recommended not to use `||` followed by any characters that can be interpreted as commands.
