OK…this is really bizarre. I have code to build a CSV from an array of data that runs fine in preview in the editor but crashes in a browser: Request failed with status code 413 I would have expected this to be a file size related error but the file size is tiny - about 250KB when it completes in …

Simon are you trying to just export a query into CSV? I have done this with a few sites by using an iFrame on the frontend. You can use your web module to query and map your data but the building of the csv and exporting can be done with the iFrame. Here’s a brief example of how to do this: Page C…

What’s the size of the buffer for 620 entries? (buffer.length will give you the size in bytes). I see from our docs that the limit should be 1,000MB which I doubt your file is reaching but perhaps it’s hitting some other hard limit. Also interesting how it works in Preview mode and not production. …

Hi Anthony, Thanks for looking into this. The buffer.length is 285633 bytes. So basically it’s tiny. I can’t imagine why there’d be a limit on a CSV file of about 1350 rows…and yet, here we are… The site has 120GB media storage. Most of it is unused at this point. I already tried switching users…

Support is definitely the way to go for this. From your description and the code above I don’t think there’s anything wrong with the code. I’ll also ping internally to see if we can get someone to look at this. Edit: Can you also share your support ticket ID here so support can reference this thre…

Hi again Anthony. The support ticket is Request 125598472. They’re asking a for screencast too, which is a challenge for me at the moment as I am on holiday, but I am hoping they can manage without that…they may need some encouragement though, so I’ll tale any help I can get thanks. Simon.

Got it. The support team is aware and looking at it. Not sure if the screencast is a hard requirement. You’ll need to follow up with them if it is.

Well after more than 2 weeks waiting, the dev team have invented a “request payload limit” in a web.js operation of 512KB. Not documented anywhere that I can find but that is what is causing this…and presumably it’s not applied in Preview Mode. This is their reply in full: After a very thorough i…

I understand the frustration. Another option you have is to use generateFileUploadUrl - Velo API Reference - Wix.com and then use fetch/axios or another library to HTTP PUT your CSV file to the generated URL. So: Generate a file upload URL in a web method and return it to the frontend On the fro…

Thanks Anthony. Will take a look later. This job has already taken me way longer than expected, without hiccups like this.

So it turns out that the failure isn’t in the back-end at all…the back-end call fails when you try to send this much data to it…the limit is either 512kb or 512KB - the limit is very confusingly spec’d and communicated by Wix. So QA suggested that I write the content to a collection as base64 encod…

I broke the number of chunks in each bulkInsert down to a smaller number and it is working now. Can’t say I am happy with how I reached this point but at least my client gets what he wants.

You can also use a CSV NPM if you want to do it from the backend.
