Java script start to fall

I understand that you did an upgrade to js.
since then I have a customer with no working system.
the problem is when I try to get length of column that is a relation column but with no object.
instead of get 0 I getting null.

therefor the system run the .catch method and not letting me move forward

you asked a link for previous version of JS-SDK, and here is the link
did you add it into your app?

getting error Failed to load resource: the server responded with a status of 500 ()

can you see content of the file in your browser if you just click on the link?

I see the code inside

alright, let’s figure out why you get 500 Error in your app

[Error] Refused to execute as script because “X-Content-Type: nosniff” was given and its Content-Type is not a script MIME type.

yeah looks like it’s because of ?_=1549275039632 query

just replaces the link, how can I avoid it?

it’s somewhere in jQuery in $.getScript method, so I think the best/faster way it is copy content of the file and put it into your files in Backendless app

it will be simpler if it will return zero value if there is no relationship instead of searching and patching.
it worked before, why you changed it?
the problem is in Backendless.js

we’ve changed GET to POST method for Data.find for avoiding url limit, and it works except “autoload” relations, and our engineer is already working on it, and it will be fixed as soon as possible, ticket number is: BKNDLSS-18085

I’ll revert the changes in JS-SDK and release a new version, so you can revert in your code and the new version will be available in a few minutes

fixed the version that you have by myself.
now it’s return 0 value and not null.
i will keep my version, and check new version before uploading them.
can not allow myself another problem of several days client can not use the system.
check your QA dep. something are not working good when going to production
