Cannot POST to Blob Endpoint `client-error`

Describe the bug
Attempting to POST a blob to the /blobs endpoint on CWBI-DEV results in a client-error response.

We were not able to find anything in the grafana logs (pretty full...) and there was no incident identifier returned.

We tried in swagger too and got the same response

Expected behavior
Expect a 204 or 200 and a blob to store

Logs/Incident Identifier
When you receive an error if possible add your corresponding log output. This will be from the Tomcat logs.
Could not see anything in tomcat, no identifier returned. Could it be the WAF?

Additional context
Working with @inguyen314 to store new blobs to DEV and not currently working

Start by reproducing the POST request from the issue against the /cwms-data/blobs endpoint, then inspect the available Tomcat and Grafana logs for the failed request. Done means identifying why the request returns client-error and confirming that a valid blob POST returns 200 or 204 and stores the blob.
