Date Parsing Exception

Adrian_Ispas · December 30, 2020, 3:51pm

{
"___jsonclass": "com.example.Boost",
"created": "1609182528000",
"___class": "com.example.Boost",
"startTime": "1609182529000",
"endTime": "1609343473000",
"ownerId": "7D9E8E96-227F-C0A6-FFC9-7446F67E0300",
"updated": "1609339873000",
"objectId": "40A3672E-DFFB-426D-BDA5-3ABF3AF16D2F",
"___dates___": [
    "1609343473000",
    "1609182528000",
    "1609182529000",
    "1609339873000"
]

}

When parsing this object I receive the following exception:
[__NSCFString timeIntervalSinceReferenceDate]

The object class in Backendless tables is DateTime.

I have set the mapping for the class:
Backendless.shared.data.of(Boost.self).mapToTable(tableName: “com.example.Boost”)

This happends when invoking custome APIs.

Any help with this is appreaciated.

Thank you,
Adrian

Hi Vlad,
When do you think you will be able to investigate this, its quite frustrating.

Work around suggestions?

Thanks

Hello @Reece_Smith

We are working on this issue, as soon as there is some result we will inform you additionally in this topic.

Hello @Adrian_Ispas, @Reece_Smith,

Issue is fixed in Swift-SDK v6.2.0. Could you please check and verify whether it works now?

Regards,
Olha

Adrian_Ispas · January 14, 2021, 2:43pm

@olhadanylova
Dates are working fine with the new sdk update.
Thank you

Adrian_Ispas · April 16, 2021, 6:53am

@olhadanylova it seems this bug has returned

olhadanylova · April 16, 2021, 7:30am

Hello @Adrian_Ispas,

I’ll check as soon as possible.

Regards,
Olha

Reece_Smith · April 16, 2021, 7:32am

Thanks Olha, this is causing our app to suddenly crash, bad timing as it’s currently being tested by clients. Something server side must have happened.

olhadanylova · April 16, 2021, 10:30am

I’ve reopened the internal ticket BKNDLSS-21294 for this issue. The problem is on the server side and our backend developer will look into it as soon as possible.

Regards,
Olha

olhadanylova · April 16, 2021, 10:58am

UPD:
I’ve checked with Swift-SDK v6.3.1 and everything works fine.
Please make sure you have the latest version of SDK.

Regards,
Olha

Reece_Smith · April 16, 2021, 11:38am

Olha,

We’re on this version, the app was working fine up until yesterday evening, something has been pushed out server side that is causing this.

This is one of the objects that fail to map to Date. All types of Dates, even the detault upate/created dates are strings

Could you please provide your APP ID, I assume the reason is in the minus symbol and therefore it is really the server issue.

Olha

Adrian_Ispas · April 16, 2021, 12:54pm

Here is the app id:
08B538C0-0E98-1827-FF98-7DF8AFF96600

Adrian_Ispas · April 16, 2021, 1:49pm

Its not the minus sign. These dates also crash

I’ve created the internal ticket BKNDLSS-24821. Our developers are already looking into this problem.

Hello @Adrian_Ispas

Negative values are because you have created/updated with values 01/01/0001 02:02:04 in the table Backendless. Have you imported those records?

Adrian_Ispas · April 16, 2021, 2:54pm

I think they are imported, but my guess is it shouldn’t affect the way a Date is created, its still a time interval.

There are other dates, like in the example above that dont map corectly.
They worked until two days ago.

mark-piller · April 16, 2021, 4:13pm

@Adrian_Ispas could you please clarify how the problem is manifested? Is it a date parsing exception? or something else? I went through the conversation in this thread, but I do not see the exact symptom of the problem.

Thanks,
Mark
