Syntax Error: Expected end of stream at char...

Encountering the error message SyntaxError: Expected end of stream at char... X can be perplexing. This issue arises when JSON.parse() detects unexpected characters or formatting anomalies in the JSON string. Common causes include trailing commas, improper use of single quotes instead of double quotes for property names, or the presence of unescaped line breaks within string literals. In my case, this syntax error occurred when attempting to parse a response returned from a call made to a Suitelet.

About the Syntax Error

“SyntaxError: Expected end of stream at char 1427860”.

This error is an indication of an issue with the string that is being attempted to parse.

In my case, for an unknown reason, “/n/n/n/n” was appended to the end of the response object string being returned.

Resolving this Syntax Error

There are multiple ways of resolving this error. The way I found to be consistent was getting the last index of the closing bracket to the response body object and removing all characters after that index.

Resolve this issue by completing the following steps:

// get last index of closing bracket var lastIndex = suiteletResponse.getBody().lastIndexOf('}'); if (lastIndex !== -1) { // trim characters after last index of closing bracket from response body var trimmedResponseBody = suiteletResponse.getBody().slice(0, lastIndex + 1); } var suiteletResponseBody = JSON.parse(trimmedResponseBody)

Parsing the trimmed response should give you a properly returned object!
