Error in the report section in the combined report

Once I request the report in the combined section I get the following error:

Combined report section

Error

Can you please help me?

Version?

Version 5.7

Have you tried the latest version?

I have not tested version 5.8 because if I build all the code, I lose the mysql database. Is there any way to save / export the database and then replace it?

Why would you lose the database?

The database is created new once you redo the build, isn't it?

We don't re-create the database. Where did you get your information from?

Also what exactly do you mean by build? If you're not using the official release and build from the source code instead, that's something you should mention upfront.

I don't think I have explained myself well, excuse me.

When you compile the code and get the traccar.run, and then run it on an ubuntu machine, the directories and so on are created. Then I create the mysql database (everything mysql related is configured), and then the traccar.xml file is configured.

What I am getting at is that if I do this same process again with version 5.8, I have to do this all over again on a new ubuntu machine. And that's what I want to avoid.

If there is any other way to do this we can talk privately and let me know.

Thanks Anton,

Let's see if I can follow the guide.

In step 1, do you know in which directory is the mysql database to backup?

If you use MySQL, read their documentation on the backup process.
