The below expression rule is used to get the http url as output and is working fine in the expression rule object but whereas if the same rule is using inside of the body of mail and script task it is not returning anything.

a!localVariables(
local!startProcessLink: a!startProcessLink(
processModel: cons!TEST_PM,
processParameters: { id: ri!id, }
),
local!cacheKey: index(local!startProcessLink, "cacheKey", ""),
tostring(if(
a!isNullOrEmpty(local!cacheKey),
"",
concat(
"<a href=""",
"">companyname.appiancloud.com/.../iYBQhUjyCxCUquoIwiZAuYZ6ZpfD3jPtesTVSHGdu6Crrx8JJi3pPg
local!cacheKey,
""">link text</a>"
)
))

you can not use start process link in a expression rule this way. you can use this function in combination of link Filed or using dynamic link. If you can let us know the use case then we can assist you in a better way.

I don't think a process can be started this way. What are you trying to achieve with the above code and where is it written?

The above code is used to return the URL for the particular task and is written in interface and we tried in expression rule, While testing the rule in the expression rule it is returning the URL, but whereas when t is used in the body of the mail and also in the script task also it is returning null values.

You can only link only with a link parameter and that needs to be clicked in order to execute. So you might have to build an expression rule that does that work for you and call it in a script task to get the output.
