Regex to extract portion of raw error message (Stripe / stripe.js) [SOLVED]

Need help APIs
#1

Can you please help with the Regex syntax to extract the “message” section of the below raw stripe error. In this case, the message I am trying to extract is “Your card was declined.” - however, I would like to use a generic approach that will work on all similar Stripe error messages please.

Raw error from Stripe.js Plus - Update a customer's details: {
 "error": {
   "message": "Your card was declined.",
   "type": "card_error",
   "param": "",
   "code": "card_declined",
   "decline_code": "generic_decline"
 }
}

I am open to other ideas too on how to accomplish the same result without Regex. Essentially, I am trying to populate a generic alert with the correct stripped-down error message from Stripe. Thanks for the help!

If you’re using the Stripe.js plugin I am pretty sure you need to create an element event workflow:

and set an alert by pulling the error message from the token:

@philip - thanks. However, I am actually in the Charge portion of the workflow, rather than the Create Stripetoken portion of the workflow, so I don’t think that the This Stripetoken error provides the Stripe charge-related errors.

@CoBubble - any suggestions please?

Also, for everyone else, please send your Regex ideas as mentioned below (@NigelG @romanmg ?) Thanks!

Ah I see, didn’t realize that. While I play around with some ideas, check out http://regexr.com/ – a very helpful tool while learning regex.

Thanks @philip!

@mishav - perhaps you have some suggestions please?

Thanks all!

Try this regex:

(“message”):\s*([^,]*)/ig

…then further modify this by truncating the beginning 12 characters and truncating the 1 ending character. You may not need /ig depending on how Bubble parses this. I am sure there are improvements that can be made to this regex (in order to prevent having to further truncate), anyone is welcome to chime in :slight_smile:

#7

Thanks @philip - I can confirm that it doesn’t work with /ig. When removing /ig it yelids:

"message": "Your card was declined."

So, we’re getting close. I’ll play around with it - thanks again!

Yes, that’s what I meant by needing truncate the beginning "message": " and ending ". You can do this within the Bubble editor. IMO the easiest route would be to save the resulting "message": "Your card was declined." as a custom state on your alert box, then on the alert box truncate this text you’re calling from the custom state itself.

#9

It’s interesting, because after the Regex is added to the Bubble editor, the Truncate function vanishes…

#10

Sorry just edited my last post, try this. (ideally this would all be done in regex as you requested, I’m still working on it :slight_smile: )

#11

Thanks again @philip!

#12

So, as the final solution, I used two find and replaces to remove the extra leading and trailing content:

Also, I found that this Regex worked:

"message": "([^"]+?)(?=").*

Thanks again @philip - I really appreciate the help.

I like the solution @philip and @collegefund.me! We’ll definitely look into improving error handling. :slight_smile:
