Had same issue on that.

My template look like this before :
```xml
...
            <field name="email_from">

                {{ (object.company_id.email_formatted or object.email_formatted).replace('\n', '').strip() }}

            </field>
...
```

But this new line create empty space in the email from

I resolve it just by putting all stuff in one line.
```xml
<field name="email_from">{{ (object.company_id.email_formatted or object.email_formatted).replace('\n', '').strip() }}</field>
```

Hope this will help some one out there

Hi,

The error indicates that you have line breaks in your email address, subject, or similar fields. Remove those line breaks, and the issue should be resolved.

Hope it helps
