[dcm4chee-arc-light] Error 409 on HTTP-POST of DICOM-SR using STOW-RS

[Naveed Pasha]

Hi everyone,

I'm trying to create a web app using the "dicom-rs" and "yew.rs" library (in the Rust programming language). I get a 409 error.

Request (generated by my code as seen in Firefox):

Not sure why it could not commit transaction...

Can anyone help?

So, I looked through the logs at `/var/local/dcm4chee/wildfly/logs/server.log` and long story short: SeriesInstanceUID is required.

The error reads "RolledbackException" because an attempt to execute SQL failed because there is a constraint some table (I don't know which) that SeriesInstanceUID cannot be null.

So I added that and it works now.

Moral of the story: Check the logs.

It helps to know which class will generate the log which in turn means that being familiar with the dcm4chee-arc-light source code makes life simpler (although I can understand this is not everyone's cup of tea).
