InvalidOperationException Invalid non-ASCII... Raspberry PI 3B+

[Greger Olofsson]

Good morning, all!

I've started a new project and plan to run it on a raspberry pi 3b+, but I run in to the following exception when I try to start RavenDB.

{

"Url":"/eula/index.html",

"Type":"System.InvalidOperationException",

"Message":"Invalid non-ASCII or control character in header: 0x2212",

}

This is when running as a daemon as per the instructions in the readme.txt.

I get the same error, but not for index.html, but rather external-lib.js and others when I run run.sh directly. 

Then index.html loads (but it's a white page) but js etc fails.

New install on latest Raspbian.

RavenDB 4.0.5 for raspberry pi.

Any ideas?

Regards,

Greger

Can you send us a fiddler sessions for those requests?

I got a tiny bit closer now.

In order to access the pi from my dev machine with fiddler, I changed the server url from 127.0.0.1 to 0.0.0.0 and added Security.UnsecuredAccessAllowed: PublicNetwork.

Now I get to see the raven but the other requests still fails.

Thanks, that is really valuable.

I still don't understand how that can be. Kestrel is complaining about invalid header value, but the only headers that I have here is:

https://github.com/ravendb/ravendb/blob/v4.0/src/Raven.Server/Web/System/StudioHandler.cs#L565

Just to check, you are running this in little endian mode, right?

I don't know anything about that, really. How can I check?

[Adi Avivi]

Hi Greger,

Little endian check:

```

echo -n I | od -to2 | head -n1 | cut -f2 -d" " | cut -c6

```

you should get "1" if it is little endian os,

1) And for the more important question: what is your distro ?

    I've tested 4.0.5 on Raspbian Stretch, and it starts.

2) Please re-verify that ~/RavenDB/Server/settings.json file does contain "ServerUrl": "http://0.0.0.0:8080"

3) After the verification (please send here the content of setting.json), `sudo shutdown -r now` your pi.

Tell me what you've got.

p.s.

Did you change the locale on the pi? (i.e. using raspi-config / Configuring locales, etc)

Oh yeah, I did change that to swedish locale.

I switched back to en_GB utf-8 and that works!

[Oren Eini (Ayende Rahien)]

This is very strange, I tried reproducing this using:

Thread.CurrentThread.CurrentCulture = new CultureInfo("sv-SE");

Thread.CurrentThread.CurrentUICulture = new CultureInfo("sv-SE");

But I'm not seeing anything strange there.

What was the exact setting you used?

Never mind, we have a pretty good idea where the issue is.

Will be fixed shortly

[Greger Olofsson]

Cool. Always impressive to see your quick turnaround for bug fixes!

For the record, I had my pi set to sv SE utf-8.
