Creating Shortcut in fabric to Datalake, Getting invalid Credentials but my credentials are correct

Hi DebbieE - Thanks for posting to the community.  I understand you created a new lakehouse and are now trying to create a shortcut. 

• Are you trying to create a shortcut in the same lakehouse that you just created?
• What are you trying to create the shortcut to (what is the target)?
• Are you the owner of the target resource connection or has it been shared with you?

Imagine you currently have these Fabric artifacts:

• A lakehouse named "Contoso Lakehouse"
• A lakehouse named "Adventure Works Lakehouse"
• A cloud connection to an ADLS Gen2 account named "Sales".

If you'd like to have one lakehouse that has shortcuts to each of the Fabric artifacts listed above, do this: 

• Create a new lakehouse - we'll call this 'Bronze Lakehouse'.
• Open Bronze Lakehouse.
• Click Get Data > New Shortcut
• Choose Microsoft OneLake, select Contoso Lakehouse and then choose the location in the lakehouse that you'd like to be used as the target for the shortcut.
• Repeat for Adventure Works Lakehouse.
• Repeat for ADLS Gen2, but choose ADLS Gen2 instead of Microsoft OneLake. 

If you encounter an error or a challenge in creating the shortcuts using steps like I've listed, please reply with more information about the step at which you encountered the issue and include screenshots so I can continue to assist.
