Missing line info from syntax error message

[janosroden]

I have an issue with TemplateSyntaxError.__str__() meaning it doesn't show the relevant line because its translated attribute is True. However both source and lineno are correct.

I'm just started using the lib so I don't know the deeper cause, but my use case seems legit:

with open(htmlTemplatePath, 'r') as f:
   htmlTemplate = jinja2.Environment().from_string(f.read())

The str(err) is unexpected '}', but what I expect is

unexpected '}'
  line 354
    <td rowspan="2" class="primaryTableHeader verticalTableHeader">{{ PH }???}</td>

If I set err.translated = False I get that helpful message.

Environment:

• Python version: 3.8.10
• Jinja version: 3.1.2
