power bi api javascript 'TypeError: Cannot read properties of undefined (reading 'get')'

[ryankang]

if i run 'npm start' in javascript, i see the 'TypeError: Cannot read properties of undefined (reading 'get')'

i don't know what is the reason for this error.

i run this same code in 2021, there wasn't any error in vscode. 

please let me know the changes of the sample api code in power bi.

Hi @ryankang,

May I know whether you will see any report load issue when you get this error? Are you embedding your report with embed token?

Hi. @v-cazheng-msft

1) when i type 'npx nodemon app.js' 
    working well without any error 

2) and when i open localhost:5300 in the chrome browser 

also working.

3) but screen is changed to white without any changes few seconds later.

4) so i back to the vscode, i can see this code error.. 

5) and i don't know exactly how to embed token to my code.
if you know the way, please let me know the reference..

i followed this address : 

https://docs.microsoft.com/ko-kr/power-bi/developer/embedded/embed-sample-for-customers?tabs=net-cor...

i've been looking for the answer for 2 days.. it's so anoying 😞

And additionally i got PPU license from MS temporily for 60 days.

If it would be reason for this case of error? 

I need to get license PPU without freeware license?
