ERROR Serializer control_serializer.cpp:511 Bad data, entry offset….

[ToivaMa]

I have been installed these:

• RasPi4 new installation.
• Nodejs
• GIT
• meson
• python3
• Ninja
• libcamera
  After this camera works Ok.

Then i make own cert by mkcert. And then get this message:
raspcamera1:~ $ libcamera-hello

Hello, Can I ask why you're making your own certificates?
The error message shows that the certificates are not valid (Public key not valid) which is then running the IPA component as an isolated module. That seems to be failing, so it's certainly a bug - but I wouldn't expect you to need to make your own certificates to sign the IPA.

The error:
libcamera-hello: symbol lookup error: /lib/aarch64-linux-gnu/libcamera_app.so: undefined symbol: _ZNK9libcamera11ControlList8containsERKNS_9ControlIdE

Makes me wonder if there is a mismatch between the compiled libcamera, and libcamera-apps too. Did you self compile anything?

Hello @kbingham,
I made a certificates for the Nodejs web application. Nothing was compiled.
I think i do new fresh install without mkcert.

In fact I think we have a fix for this one already

I think this is the same issue as being solved by this patch.

https://patchwork.libcamera.org/patch/17292/

Another solution for this is to install openssl locally. That should fix (workaround) the
[21:35:00.098312980] [4146] WARN IPAManager ipa_manager.cpp:113 Public key not valid
error print, and the secondary failure then won't occur.

That's definitely all due to changes in libcamera - so we'll get these resolved as soon as we can.

Have you tried the latest libcamera branches ? I think these issues should be resolved. If not can you let me know please?
