Cannot set property of 'action' error

[julianfrank]

I have a normal Express app and I included this line as per your website instructions

if (process.env.NODE_ENV !== 'production') { require('@glimpse/glimpse').init() }

Now when I try to open my app it shows this error

TypeError: Cannot set property 'action' of undefined

@julianfrank Thanks for sending through the report! Are you doing anything in your express pipeline that might be considered "unusual" or packages that might be in the pipeline that the typical scenarios mightn't have?

[julianfrank]

Lots actually...I've got the whole std parsers,helmet, and socket io....It is not a simple app....

From looking at the code, we've lost context for some reason. @julianfrank - any chance you can get us some code that repros this so we can dig deeper?

@julianfrank can u make sure glimpse init code is the very first line in your app.js? Even before express.

[julianfrank]

Yes

@julianfrank - we believe this error is fixed with our release coming up in a few days, or next monday at the latest. If you'd like to try out a pre-release build to see if it addresses your issue, you can do the following:

npm config set @Glimpse:registry=https://www.myget.org/F/g-alpha/npm/
npm install @glimpse/glimpse
npm ls @glimpse/glimpse # this should say v0.21.3 or higher.

[julianfrank]

I tried the steps and it only updated to @glimpse/glimpse@0.20.9 and not c0.21.3!

In 0.20.9 it still sadly fails :(

Try pinning the version:

npm install @glimpse/glimpse@0.21.3

[mike-kaufman]

Fix for this is availabe on NPM now with glimpse version 0.21.5.
