Cloud Foundry: Node-Red app crashing with 500 Error: Failed to establish a backside connection

Question

I have created an application in IBM cloud - using the Node-Red starter. The app has been running with no errors for 2 weeks.

I have installed an additional node:"node-red-dashboard":"2.9.6", by adding this in the package.json file.

When deploying within Node-Red, the app crashes with error "Cannot connect to server". Then, the page is no longer reachable with error "500 Error: Failed to establish a backside connection".

I have tried to restart the app, which allows it to run, again until I deploy again.

This could be an intermittent problem with the toolchain or possibly due to the extra memory requirement placed on the build with the additional node.

Is there a reason why you have not used the manage palette option to install the new nodes?

If you are still getting the error, try increasing the memory allocated to node-red in the manifest.yml file, or try removing the additional node to get node-red to rebuild.
