[422] Invalid Parameter despite filtering out bad character

I have a scenario that ends in a custom API to do a POST call.

 

It's throwing an occasional "[422] Invalid Parameter" error. Apparently, some users are pasting control characters (namely TAB) into task names and when fusion throws them into the JSON response it's failing.

 

I've tried using the ascii() function, which seems to strip the character out, but the error is still being thrown, which I don't understand at all.

 

Thoughts?

Fair enough. 
2 options: 

  1. the replace() function if you know it's really a tab only
  2. use the regex module to remove any characters that are NOT allowed. 

 

[^a-zA-Z0-9\.\-\(\)\[\]\{\}'":;\/,\-_\+ ]​

 

  • Some characters have a back-slash because they have special meaning in RegExp.

Try Trim()?

 

That should take care of whitespace - not sure about other non-printing characters

Trim() only takes care of the beginning and end of the string, the ones I'm dealing with are in the middle.
