Error when opening dev tools

General

Hi Node Red users,

I have a docker container with node red.
And every time I try to open my browsers developer tools, the container exits with the following error message:

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.

anyone have an idea how to debug that?

Can you share the versions of nodejs, node-red and dashboard that you are using?

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 problem seems to have gone with bumping the Node-Red version to 1.0.4, and node version 10, or maybe a restart. :slight_smile:
