Hello,
I might need more details to help you find the problem. Can you show me your gumu.js and X3 code please?

Thanks

Thank you so much for your reply 

gumu.js code is as below

Sage X3 Code to call gumu.js file

Hi Alvan-M  hope you might be able to review the code please.  Appreciate your time and efforts

Stacey Orrock the input into variable MODULE 'bundles\aptus\lib\gumu._js' contain invalid JSON string characters, namely '\'. Change the input to 'bundles/aptus/lib/gumu._js'. You can validate that your input does not contain any invalid JSON characters by using the escjson function, i.e. MODULE = escjson(MODULE).

Thank you for your response we tried that and got

Stacey Orrock the error indicates that the Java script you are attempting to execute or one of its dependencies cannot be found. Not sure which version of Sage X3 you are working with, or which JavaScript you are attempting to execute.

Hi we where just testing with the blog from Greytrix and could not get that to work.  we are using V12 pu33.

Thanks

Stacey Orrock with since V12 your declaration inside your gumu.js should be:

var httpClient = require(“@sage/syracuse-lib/src/http-client/httpClient”);

instead of:

var httpClient = require(“sage/syracuse-lib/src/http-client/httpClient”);

Hi Stacey Orrock ,
if you are trying to encode and decode in base 64, what don't you use native 4GL instructions ?
online-help.sageerpx3.com/.../

I believe that the question was targeted towards the use of javascript libraries rather than the use of encode, decode in base 64. The base 64 encryption was just the example that was used.

Hello Alban-M ,

I've follow your tuto line after line but I still have the same issue :

Do you have any idea of what can be the problem ? 

Thank 

Jules
