SQUARE does not work in sandbox mode

Getting this error when submitting with square in sandbox mode.

Error when calling Transaction: [HTTP/1.1 404 Not Found] {"errors":[{"category":"INVALID_REQUEST_ERROR","code":"NOT_FOUND","detail":"Card nonce not found in this application environment. Please ensure an application ID belonging to the same environment is used to generate the nonce."}]}

Hey there!

happy to help you today.

I would like to inform you that, make sure test mode is also turned on available under additional gateway settings before you tried to use the sandbox.

I have reviewed your settings and test mode is currently NO as shown in this screenshot below. 

Try this and let us knwo if it helps.

Thanks.

That is not the problem.  I have updated and still get same issues.  I have seen this posed several other times.   Seems like in November square changed their APIs and jotform needed to make a fix.  That was over 6 months ago.   Is there no way to use test mode with square?  It seems that way.

Similar Thread from November:

I wasn't able to replicate the issue on my end. I have set up a new form with a Square field on sandbox mode added to it. I was able to submit it with no issues.

Here's the form: https://form.jotform.com/201516261835047 

Please ensure that you are using one of these cards to test: https://developer.squareup.com/docs/testing/test-values 

And as my colleague has mentioned, you have integrated the field on TEST MODE but you haven't toggled test mode in the Advanced Settings. That is the reason why you received that error:

It should be toggled to YES.

Please try reconnecting, toggle the TEST MODE to yes, then click CONTINUE at the bottom to save the changes.

I also suggest that you test the form on an incognito tab to ensure that browser caches won't affect the submission process.

Not sure your example form works or not.  I can put nothing in the fields and it still submits.

Why are there 2 fields that control putting it in test mode?  That seems confusing.   The 2nd value will not save for me.  I have tried 20+ times.  I have deleted the entire widget and started over.   No matter what, if I leave the jotform edit, go to something else (ie another jotform) and come back the "Test Mode" field will be set back to No.  It is impossible for me to keep it saved.   How do you keep it saved?   See below

This is with it saved.

Then this is when I go to another form and come back.

Could be a cache issue. Please refer to these steps:

1. Open an Incognito Tab, login to the account, and open the form in the builder

2. Disconnect your Square account in the Square field

3. Delete the Square field

4. Add a new Square field then select TEST MODE in the MODE option. 

5. Toggle YES in the TEST MODE option in the ADDITIONAL GATEWAY SETTINGS (if not toggled to YES)

6. Connect your Square account.

I tried all that and it did not work.   I even created a new form with nothing but simple square widget and get the same error.  It will not save the Yes on the TEST MODE in Additional Gateway Settings on this form either.   Very weird.
