Response when executing /saveScan ... in Swagger

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>502 Proxy Error</title>
</head><body>
<h1>Proxy Error</h1>
<p>The proxy server received an invalid

response from an upstream server.<br />

The proxy server could not handle the request <em><a href="/locdb-dev/saveScan">POST&nbsp;/locdb-dev/saveScan</a></em>.<p>
Reason: <strong>Error reading from remote server</strong></p></p>
<hr>
<address>Apache/2.4.25 (Debian) Server at locdb.bib.uni-mannheim.de Port 443</address>

On local development setup, there is a cross-origin error:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://locdb.bib.uni-mannheim.de/locdb-dev/saveScan. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

Both locally and in the deployment setting the tests are still green. Further investigation showed that there were two problems related to this issue:

  1. server crashes when invalid form-data parameters supplied; Fixed with locdb/loc-db@6e7d59b
  2. server crashes on multipart/form-data when headers are set erroneously due to a middleware problem. Apparently some dependencies changes; Swagger-UI is also related to this issue

Problem 2) needs further investigation and maybe a temporary workaround but the front-end should now not encounter problems anymore if the requests are sent correctly.

Back-end problem 2) solved with locdb/loc-db@4286c4d

Great, we should keep in mind that the PPN needs to exists in SWB.
