Event forwarding throws error

Hello,

i've setup traccar version 4.6 and enabled event.forwarding
my traccar.xml looks like this

    <entry key='config.default'>./conf/default.xml</entry>
    <entry key='notificator.types'>web,mail,sms</entry>
        <entry key='database.driver'>com.mysql.jdbc.Driver</entry>
        <entry key='database.url'>jdbc:mysql://127.0.0.1:3306/traccar?serverTimezone=UTC&amp;useSSL=false&amp;allowMultiQueries=true&amp;autoReconnect=true&amp;useUnicode=yes&amp;charac$
        <entry key='database.user'>traccar</entry>
        <entry key='database.password'>**Filler**</entry>

        <!-- event forwarding -->
        <entry key='event.forward.enable'>true</entry>
        <entry key='event.forward.url'>http://**Filler**/traccar/events</entry>
        <entry key='event.forward.header'>
            content-type: application/json,
        </entry>

</properties>

this is the warning/error message in my log file:

thanks in advance

Remove comma from the header.

thanks for the quick reply, i changed it:

        <entry key='event.forward.enable'>true</entry>
        <entry key='event.forward.url'>**Filler**/traccar/events</entry>
        <entry key='event.forward.header'>
            content-type: application/json

but unfortunately i have still the same error:

any other ideas? could the message be to long?

It still indicates that there's an error with the header.

Ok i tried it completely without the header lines and now it works.
i added the content type because my application explicitly checks for the content type. but it seems that it is automatically added to the header even without my lines
