Ui_button missing after node-red-dashboard upgrade

After upgrading the node-red-dashboard palette from v 2.13.2 to v 2.19.3 ui_button type disappered from the palette and my flows having button element didn't start anymore.
The message error is the following:

Flows stopped due to missing node types.

  • ui_button

Close

Node-red v. 0.19.5 running on docker.
I've already tried to restart the node-red docker - after upgrading the node-red-dashboard palette from within the Editor - but with no success.

Any thoughts?

Which version of node.js are you using ? Dashboard requires at least node v8, but even that is past end of life so 10 or 12 preferred. Core Node-RED is now at version 1.0.3 also...
If you need to stay where you are then you may need to revert by using npm i node-red-dashboard@2.13.2 or some lesser version that does work.

Tomorrow I'll check it and let you know. Thanks for your prompt support.

After running the Node-Rer docker and entering the docker (by using docker attach node-red command) I get the following error

Your flow credentials file is encrypted using a system-generated key.

If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.

You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

The node version provided with the docker image I use is node v6.16.0.

From the log it's clear that the dashboard module (after the upgrade to the last version from within the NOde-red IDE) didnt't load anymore. Is there a way to update the node-dashboard from within the node-red docker container? Do I have to launch the command you suggest me (npm i node-red-dashboard@2.13.2) when I'm attached to the node-red docker?

Otherwise I was thinking to to delete the node-red docker instance and create a new one (after backing-up flows, settings and credential files).. What do you think its the best option?

As long as you do the backup then yes I would start with another new docker container from https://hub.docker.com/r/nodered/node-red as that is up to date.

Solved by pulling the last Node-Red docker image and run a new container from that. This solved the dashboard problems.
