Local install of JSReport crashed - now won't start

Adam Richards

As the title says, I have a local install that I've been experimenting with, and it's been working fine. I was working on trying to get some external data with scripts, when my computer crashed (blue screen - Windows 10). Once it did the disk scan and repair, I tried to load jsreport again from the command line and get this error each time.

The odd thing is the error it's reporting about unexpected token in json at <anonymous> is the problem I was trying to debug in my script when the computer crashed.

I've tried jsreport repair but it hasn't fixed the problem.

Any ideas?

please backup/delete file data/settings and start again.

Which version of jsreport you have please? We will need to investigate how the data became inconsistent, it should not happen.

Adam Richards

I'm on 2.1.0, but I can't find that file to delete?

jan_blaha

It should be there, please paste screen of your data folder.

Side note - you should create an extra folder for jsreport app. As we instruct now on the download page. You seems to be running directly from the user folder.

Adam Richards

which jsreport folder will the data folder be in? I'm not overly familiar with the structure.

jan_blaha

The default is
jsreportappdir/data - data folder
jsreportappdir/jsreport.config.json - configuration file
.....

Adam Richards

I'm removed it and get the same error.

jan_blaha

There could be another file in the root of data folder that is causing the problem.

Please zip your data folder and send it to my email. Remove the secret information.
Thank you.
