algorithm' cannot be a 'null' or an empty object" error

[sognen]

Hi,

With the latest build I am getting an " 'algorithm' cannot be a 'null' or an empty object" error. See under for relevant log entries.
I do not see this with v 1.2.0.124.

br,

I upgraded the IdentityServer libraries. In this version they changed how they serialize the tempkey when using the developer mode token generation, which is usually fine because you aren't supposed to use those beyond development. It also renames the tempkey.rsa file to tempkey.jwk, in a different format.

This means your old tempkey.rsa is invalid. You'll need to update to the version I just pushed (it fixes the filename change), delete your old tempkey.rsa, make sure that config/tempkey.jwk is persisted instead correctly (if you are mounting the entire config directory, you are fine already), and relink in Google Home.

But really, you should take this opportunity to move to your own signing certificates since you need to relink anyway.

Thanks, updated to the latest version and all is good.
