hi Vibhor,

you are getting above error when u had migrated ...

[vibhor_bhatnagar]

Hi Govardhan

Yes,I used quick actions to migrate the project.

Hi Vibhor ,

Iam assuming and thinking that you are migrating a develompent component, in that case , try to redo the migration again deleting the existing dc, as even i was not sure why the above error occured, i deleted the migrated dc from work space as well as at from the NWDS  first and then later i migrated the dc from scratch which didnt give me any error ...

Please follow the steps correctly while migrating.. like see if any dependent dcs are there and are they migrated already .. please let me know once you are done with the migration

Hi Govardhan

Thanks for advice!

I figured out how to correct this.

We just need to Repair Project to Correct Internal API Usage.
