Passed data from Activity to Adapter, but when I try to use data as string, it displays as null

I have passed data from my Activity to My Adapter. When I debug, I can see the correct data has successfully passed to my adapter, but when I attempt to use it as a string ( for example, if I want to set the text as the data I just passed), it shows as null.

• On the line that says " this.uniquesharedIds = uniquesharedId;" - the "uniqiuesharedIds" is showing as null.
• "uniquesharedId" shows has the successfully passed data.
• I need to be able to use the string of "uniqiuesharedIds."

Sorry if this is a silly question. Sending data from Activities to Adapters always confuses me and Im not able to find a ton of documentation/videos on the topic. Thank you.

My Activity In the On Create Method

myadapter = new Invite_Contributors_Adapter(contributorInviteList, getIntent().getStringExtra("uniquesharedId"));

The Adapter
