Read smart contacts with rjson

[PatronMaster]

Hi Experts,

I have here small program that is reading smart contracts, these smart contracts are like this

Everything was working on version 0.2.17 for rjson (jsonlite was not working).
Now in version 0.2.21, it seems not working and give following error:
Example:
Error in rjson::fromJSON("[\n ... : not all data was parsed (3707 chars ere parsed out of a total of 3963 chars).

Before was working without any issue.

Note: This was scratch installation using the same OS but with new version of all packages on R.

I noticed now it is same issue as jsonlite at least it is same place.
Error: parse error: trailing garbage

Is it possible to reproduce this bug with a smaller example?

Hi Alex
Yes, what you need exacly?
I already leave command line above
abi_load_UniswapV2Factory <-rjson::fromJSON('[....

I suspect this is the issue -- the string you have supplied is not valid json -- as a result, returning an error is the expected behaviour of rjson.
