sanic can't show request.header content

[jiamo]

After

sentry_sdk.init(
    dsn=user_config['SENTRY_DSN'],
    integrations=[SanicIntegration()],
)

and capture_exception(exception)

But the browser can't see the request.header (which is a dict value)

request body can be show but in such warning like

The first discared value is a part of request.header

Which version of Sanic are you using? We just do dict(request.headers) and the Sanic documentation does not indicate that those headers are structured/parsed in any way.

sanic 20.3

We only support LTS versions of Sanic. I will make this more clear in the docs but see sanic-org/sanic#1532 for more info.

[untitaker]

There's a doc PR open which will update the supported versions.

I would suggest to report this bug against Sanic since this seems like something entirely unintended on their end. In that case I would also attach a small repro case though.

For reference here is what we do to sanic's request headers:

sentry-python/sentry_sdk/integrations/sanic.py

Line 194 in 1f6743c

request_info["headers"] = _filter_headers(dict(request.headers))

We literally just call dict() on them and get this back, apparently.
