JSON Primitive Error V5.3.4

V5 Issue
1

All of a sudden our licensing deactivated (this is a different establishment to my previous SambaPOS post issues) and when we try to activate it we get this error. Updating SambaPOS to the newest system is what crashed our other establishments till so was hoping there was a way around this or if this was a completely separate issue.

Please update your SambaPOS to latest version.

4

he states : “Updating SambaPOS to the newest system is what crashed our other establishments…”

another solution?

5

Updating shouldn’t cause any problems. Hundreds of users are already using the latest version.

6

i am not scared about the latest version. i am scared about the update from 5.3 to 5.7 because it created problems for other (above) and in case of problem, I’ll have not enough time to fix it before the opening.

is there some intermediary version i could install instead of a big update 5.3->5.7, if yes where ?

7

The only potential issue during the migration process is the migrations themselves. If you have a very large database, I recommend performing this operation on a powerful computer. However, if you send me a backup, I can do it for you. In other words, a database that’s already migrated and ready to the latest version.

8

How do i send you a backup? 700 mb

9

You can use WeTransfer. my email is [email protected]

10

transferring… in a couple of minutes you should have the files.
I sent you 2 files:
…A.zip - 2 am : automatic backup when closing today’s workperiod.
…M.zip - 3 am: I first deleted 2 useless tables (xxx) that I (myself) had added years ago, then make a Manual backup.

11

OK. i will migrate them

12

i tried the update → all broken:
