Facing problems with Marketo Rest API: Update Landing Page Template Content

[Sabeeh_Khan]

I am trying to add some html in the landing page via API call using Postman

If i add Html code directly or stringify it, it is giving me error

{
requestId: '15bd2#19199b87634',
success: false,
warnings: [],
errors: [ { code: '611', message: 'System error' } ]
}

How should I add HTML? Is there any other way?

Solved the issue by setting the content as file and then uploading the file
