I am trying to use a scripted field as a parameter in another scripted field but it seems to give wrong result in es7.4.2,It was working fine in es5.0.1

"script\_fields": {  
"a": {  
"script": {  
"source": "return 1",  
"lang": "painless"  
},  
"ignore\_failure": false  
},  
"b": {  
"script": {  
"source": "if(params.val != null){return params.val}",  
"lang": "painless",  
"params": {  
"val":"a"  
}  
},  
"ignore\_failure": false  
}

expected output -\> value of field "a" is "1" and "b" is also "1"  
but actual result -\>value of field "a" is 1 and "b" is "a"  
can anyone tell me what is wrong with the query
