Re: [EP-tech] Import DOI Issue

We had something like this a while back. Thankfully eprints services sorted it so I don't know the details but they did say it was to do with an unexpected result from crossref. This fits with the "unhandled warning" message you have. A route might be to look at what you are getting back and see if there is code in place to handle it. The other thing they said was that they were unable to replicate it and thought it might have been related to the doi being very new in the case we provided.

Not sure if any of that helps but maybe it is a clue

Same issue and same error-message here.
A change of the URL brought no effect the error kept the same.

Any hint is greatly appreciated.
