How do I fix the error: Developer id of submitted package does not match developer id of previously submitted package.

Issue

I am trying to switch to SDK mode and I am getting this error.

We switched developers and we do not have the previous devID.

I do not remember the previous devID. 

Environment

SDK

Direct Publisher

Developer Dashboard

Answer

You can expect to see this error if:

• You recently took over development for a channel that was previously managed by another developer.
• This is the first build you've submitted since converting from Direct Publisher to SDK.
• You did not save the original devID information.

If you do not have the previous devID information, you will need to create a new one by rekeying the channel's package. Please save the new devID information for future use. Every time you have to generate a new genkey, authenticated users will be logged out and forced to log back in to view any gated content. 

There is no way to pass this Static Analysis error if you've lost the original devID information. Once you generate a new genkey, contact Partner Success to have your channel manually published. The next time you submit an update, you can use the latest key to sign your package – if you've done this properly, you should not encounter this error again.
