Spot A Shark USA

What operating system were you using? (eg. MacOS 10.15.3)
MacOS 11.2.1

What web browser were you using? (eg. Chrome 79)
Chrome Version 92.0.4515.159

What is your role on the site? (admin, researcher, etc)

What happened?
Tried to submit an encounter while logged in to my account and received the same error message, even when using different browser. Screenshot of error page below:

What did you expect to happen?
A ‘Success!’ message receiving encounter. I want to note that I was able to successfully submit the same encounter with same information only after logging out and using an incognito window.

What are some steps we could take to reproduce the issue?
Logging in to my SAS account (ara.mcclanahan) and trying to submit an encounter could possibly create the same error page.
