I want to add a Sentry breadcrumb with the node ID so when an error occurs I know what path was taken. For example,

`Sentry.addBreadcrumb({ nodeId, flowId })`

Is there some kind of node middleware that I can add this code to? So that this code runs onStart for every node?

Hi @watadarkstar

A search on [https://flows.nodered.org](https://flows.nodered.org) reveals a node that may help.  
use this along with the built in `catch` node?

> **[node-red-contrib-sentrynode](https://flows.nodered.org/node/node-red-contrib-sentrynode)**
>
> A sentry node for node-red

Disclaimer : I dont use sentry

EDIT.  
Oh hang on - you already using it - my bad 😅

Have a look at the messaging hooks api: [Messaging Hooks : Node-RED](https://nodered.org/docs/api/hooks/messaging/)

Yeah I'm already using that. It only shows me the last node where the error occurred. I want to see every node that was "visited" to lead up to the error so I have more context.

Is this for a node your developing?

Nope but may potentially add this to that package you mentioned.

Ok, unless @knolleary can correct me?  
The Hooks API is only for custom node development.

Or, PR the enhancement with the developer/fork and update it 😉  
Patching nodes (I feel) shouldn't be required, and an update will benefit all users who install such node.
