Is there a limit on number of fields in a Netlify form?

Hi!

Is there a limit of how many fields a Netlify Form can have. I have about 120 fields (… I know right…) and the build/deployment fails (just on Netlify) without an error. If I remove some most of the fields, it builds successfully. If I remove less of the fields it fails. Running these builds over and and over again to narrow it down is taking a long time and is killing my allotted minus.

Thanks!

hey there, can you link us or paste the deploy log of one of these builds that fails, please?

Hi! Sure thing! I dont know how to send a link… but maybe you have admin access to see this: Netlify App

Otherwise, below is the log (I hit the message limit so Ive replace some repeated text with “MORE DATA HERE”:

Thanks! That link was EXACTLY what we were looking for; Our Support team can see that page on your site.

From it I sleuthed around a bit in our internal logs and it appears there is some kind of formatting error in /client-intake-form/index.html . This is the error we see:

</form>: unexpected 's-name48' after '[:equal, "'spouse'"]'

Perhaps you can hunt around there and see the problem?

OH Interesting… That does help! Is there anyway I can see formatting errors like that?

Thanks! @fool

Not at present, but you can tell “something” went wrong when you see this pattern in your logs:

5:18:05 PM: Starting post processing
5:18:05 PM: Post processing - HTML
5:18:11 PM: Starting post processing
5:18:11 PM: Post processing - HTML
5:18:12 PM: Starting post processing
5:18:12 PM: Post processing - HTML
5:18:13 PM: Starting post processing
5:18:13 PM: Post processing - HTML
5:18:14 PM: Starting post processing
5:18:14 PM: Post processing - HTML

…that something like this went wrong. We should only say Starting post processing once; we have 5 retries and then give up. IT is occasionally the case that something transient went wrong - we were deploying some component of our service while your assets were processing - and a second or third try will work - but if you see 5, we generally couldn’t succeed based on something in your code.

This is the first time I’ve seen an actual syntax error like this; it’s usually a reference in CSS to missing files or something like that, so congrats on finding a new error vector :smiley:

You’re Welcome :sweat_smile:

Just in case it helps anyone else, turns out, I had a form input that ended up with some non-valid HTML. One of my inputs had a ' in the name field, and I bet the Netlify Form parser saw it and said NOOOOO (insert gif of Michael Scott here). This is the guilty suspect:

<input name="reason-for-doctor's-care" type="text">

A simple replace fixed it. Maybe in time Netlify could strip out breaking characters on their end too, or maybe some error reporting?

Thanks for the help on this one!

That would be a smart thing to do but also a challenge - our form handling service is looking for the name that your code sends, and just encoding it on our side wouldn’t affect how you send it. So this really is a fatal error - we can’t read the name of the field OR turn it into something that would “just work” for you based on the code you wrote.

But better error handling is definitely a thing we should (and are now) tracking as a feature request. We could at least tell you where the problem is since we do find out :slight_smile:
