Posted on by yaza

When I try to debug bc in visual studio code I get this error:

Error: It is not possible to add a breakpoint at line number 428 in application object type CodeUnit, ID 50417. Check that the resource exposure policies applied to this extension allows debugging.

Am I missing rights?

Hi @yaza,

you must ensure that the allowDebugging property has the value true in the app.json file.

Best regards,

Hi,

Is the object part of your extension?

If yes, then you should be able to debug the object and also able to set breakpoint.

Refer this video for debugging - https://youtu.be/TgXNXxKL2yc

I also added this to my app.js:

"resourceExposurePolicy": {

"allowDebugging": true,

"allowDownloadingSource": true,

"includeSourceInSymbolFile": true

},

Still getting the error.
