How do I attach a pdf to a message using the "SetValue" and "mediaitem" in suitescript 2.0 ?

AI generated answer (using internal Slack threads):

To attach a PDF to a message using the "SetValue" and "mediaitem" in SuiteScript 2.0, you would first need to convert the PDF to a base64 string. This can be done by POSTing the PDF to the RESTlet, which will save it as a file to the file cabinet. Here is a general outline of the steps you would need to follow: 1. Convert the PDF to a base64 string. 2. POST the base64 string to the RESTlet. 3. The RESTlet will save the base64 string as a file in the file cabinet. 4. Attach the file to the vendor record. Here is a code snippet that shows how to write a file in SuiteScript:

javascript
context.response.writeFile({
    file: myFileObj,
    isInline: true
});

Please note that this is a general outline and the actual implementation may vary based on your specific requirements and the structure of your SuiteScript. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
