Facebook strips away query params arrays

[madsh93]

I'm not really sure what to do here. But it a bit of an issue for me and my site that is heavily shared on Facebook:

If you send a Facebook Messenger message containing an array in the query params e.g. this link, which is how I understand Vue router handles arrays.

https://www.domain.com/demo?equipment_ids=26&equipment_ids=28

Facebook will strip away the first equipment_ids:

Any idea on what is going on?

I think I answered this on Discord but to add it here too: This seems like a misalignement from Messenger as it's a native feature of URLSearchParams:

p = new URLSearchParams()
p.append('a', 1)
p.append('a', 2)
p.append('a', 3)
p.toString()
'a=1&a=2&a=3'

It would be nice if you could send a ticket to Facebook Support as it would be important for them to fix it.

Thanks @posva

I've contacted Facebook but I'm not really getting through and they won't a knowledge they have a bug.

It will probably take time. Hopefully not too much 🤞
