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

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?
