Hello everyone ,

type: "error.SuiteScriptError",
   name: "INVALID_FLD_VALUE",
   message: "The field custcol_gbs_vendorreturnauth contained more than the maximum number ( 15 ) of characters allowed.",

While seting the value of InlineHTML field I am facing this issue , anyone has idea that why it is throwing this error.

Are you sure it’s of type InlineHTML? Looks more like it’s a text field with a defined maximum character limit of 15 and you are trying to set the value to something longer.
