server error and container crash when searchin with special characters

[planmacher]

When using some special characters like for example ?' or ' " ' in the search input the server throws an undefiend error and the container shuts down.
Server log shows an "Sytax Error: Unexpected end of json input"

I am using
Docker v2.0.3-edge-alpine
Windows / chrome
