So when I run the REST API query to pull the schema I get the correct results for all of the columns I have been able to verify - with the exception of FormattedID. This returns a result of INT (10) from the schema call - but the actual data type is a STRING (10) - and the data inside is obviously a string. This is breaking my scripts.
I have recreated this issue and will open an case so we can look into it further and file a Defect if necessary.
We'll keep you updated via the case.
