Traccar server issue : Zero date value prohibited - DataReadException

Hi,
recently i getting this error on get device api

Zero date value prohibited - DataReadException (... < QueryBuilder:368 < *:446 < DatabaseStorage:76 < DeviceResource:116 < ...)

my traccar version is 5.6, i have checked the logs and there everything is seems normal

What's the API request?

GET https://tracker-server/api/devices

response http status code is 400

Looks like you have some invalid data in the database. Or at least your database is considering it as invalid.

but it was working fine 2 days back, can help me how can i find that invalid value?

It's one of the time fields.

so in device table there are 4 coloumn which has timestamo datatype and i have checked there is either timestamp or null value present
lastupdate = mostly timestamp and some null value
expirationtime = all null values
motiontime = all null values
overspeedingtime = all null values

i am not been able to find any issue with the data

Try enabling full stack traces to see the full error.

I got it, actually in motiontime there was a data entry 0000-00-00 00:00:00
now it is fixed
