Base64Encode conversion error in Salesforce spoke flow action

[Rajesh Mushke]

Hi All,

I have tried all the possible ways as per different community threads but still I'm unable to convert the attachment to base64encode in Salesforce spoke flow action. getting the below error:

Error: Access to GlideSysAttachment.getContent from scope sn_sforce_v2_spoke not allowed

My script:

 var gr = new GlideRecord('sys_attachment');

 gr.get('0710e3deebb11a10e099f5adbad0cd2f');

 var sa = new GlideSysAttachment();

            sa.getContent(gr);

            ed = sa.getContentBase64(gr);

  gs.info("base64Data---"+ed);

@Rajesh Mushke You can create a Script Include in the global scope to handle the base64 encoding and then call this Script Include from your Salesforce spoke action.

Or you can explicitly allow cross-scope access by adding a Cross-Scope Access Rule.

Hi @Abhay Kumar1,

Thanks for the response! 

Cross scope access iss already present in my instance

And, i have tried with Global script include already but still no luck
