[ATLAS-4731] Entity fetch api call fails for some entity which has businessMetaData with Biginteger attributes

• Type: Bug
• Status: In Progress
• Priority: Major
• Resolution: Unresolved

Description

Using the beta interface we can see our custom typeDefs in the left hand panel

>-- localTypeDef (1,012)
custom_typedef_a (1)
custom_typedef_b (1,008)
custom_typedef_c (3)

Selecting localTypeDev/custom__b displays the list of entities in the right hand panel.
Selecting any of the results generates a "Something went wrong" popup, the rotating loading icon and an unpopulated Properties/Relationships/Classifications/Audits/Tasks page.

The following ERROR message can be seen in the ATLAS application.log :-
ERROR - [etp2052996178-280 - xnxnxxnn-nnnn-nnnx-xnnn-nxnnxnnnxnnx:] ~ graph rollback due to exception (GraphTransactionInterceptor:200)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

So while writing the BusinessMetaData for BigInteger, value=4 we do not call BigIntegerSerializer class, so i won't throw the exception.
And while access through UI it fetch data from BigintegerSerializer class and throw the Required size [1] exceeds actual remaining size [0] exception.
