SSS_INVALID_TYPE_ARG when calling http.createSecureString

Question

I am trying to access an API Secret from a SuiteScript. Everything I've read is that in its simplest form, the call is something like: let secureString = https.createSecureString({input: "{custsecret_id}",}); However, when I try that, I get an SSS_INVALID_TYPE_ARG error. Here's a screenshot with my API Secret key. It is allowed for all scripts and all domains. Boiling everything down to the most simple snippet still fails. Code (run in debugger): require(["N/https"], function (https) { let secureString = https.createSecureString({input: "{custsecret_i1_cw_api_test}"}); let anotherString = "test"; // code using secureString to follow }); Error: SSS_INVALID_TYPE_ARG: {"type":"error.SuiteScriptError","name":"SSS_INVALID_TYPE_ARG","message":"You have entered an invalid type argument: nlobjCredentialBuilder","id":"","stack":["Error at :2:29 at Object. (:1:1)"],"cause":{"type":"internal error","code":"SSS_INVALID_TYPE_ARG","details":"You have entered an invalid type argument: nlobjCredentialBuilder","userEvent":null,"stackTrace":["Error at :2:29 at Object. (:1:1)"],"notifyOff":false},"notifyOff":false,"userFacing":true} Are there any restrictions using https.createSecureString in Sandbox, or running it in the debugger? Thank you, Scott

The issue was with using the Script Debugger with a script entered in the New Script pane.  I took the exact same code, created script and deployment records, ran the script and no errors occurred.  I then used the Script Debugger with Debug Existing and that also worked.  You can close the post.
