Good question.

For us to have proper context, please post a screenshot of the Zap step that encounters the error.

I have the same error occurring when clicking the ‘publish’ button.

I’m also getting the same error. The testing works. I’m doing a zap from gmail to flodesk, but I get this same error message when I hit publish. Minified React error #426

Please let us know what we can do to fix it. Thanks!

Yes, I’m getting this error as well from Gmail to Mem. Have tried all the troubleshooting steps without success so hoping someone can help. 

Same problem here, @Troy Tessalone 


Gmail to Omnifocus.


Test is successful every time, but publishing from the editor always fails with:

Minified React error #426; visit for the full message or use the non-minified dev environment for full errors and additional helpful warnings.


If I try turn it on from, I get this:

Error turning Zap on: This data flow to is not allowed `GoogleMailV2API`

Hi @jac55673@Yohann S, @walba22, @ZapMorris and @NotZappy! 👋

I did some checking and it appears that you’re all running into these errors due to Google’s limitations for a consumer Gmail accounts (e.g. for emails that end in or - business Gmail accounts aren’t affected by these limitations. 

Currently ChatGPT isn’t on Google’s list of approved apps for use with consumer Gmail accounts. But, we’ve got a feature request open for ChatGPT to be added to Google’s list of approved apps so I’ve added your votes to that. I can’t make any promises as to when ChatGPT will be added to the approved list but we’ll be sure to notify you all by email the minute it is!

Thank you! Let me see if I can use my .com email address and see if that fixes it.

Hi there!

We got the same error 426 two days ago while trying to make a zap to connect Gmail with Slack.

Today as I tried to publish again I got the following (please,see screenshot).

But we have a business account on Gmail.  As per your info we shouldn’t have limitations but we still do.

Any ideas?

BTW, we have another Gmail-Slack zap that has been working since last December and it seems to work properly.

Could you please resend the screenshot again? Also, please send a screenshot that of the connected Gmail account and be sure to blur out a part of the account credential before the “@” symbol. Here’s an example:

Hi there @RMAA,

Thanks for the screenshots!

It looks like you’re connected using a Consumer Gmail account (e.g. for emails that end in or As mentioned by SamB’s reply above, you will need to connect a business account for you to not get affected by Google’s limitations. More about this here:

That said, if you’re still experiencing issues using your personal Gmail account alongside ChatGPT in a Zap, let us know in the Community or reach out to our Support team and we’ll be happy to help! 🙂
