I have a new Nextcloud 21 instance and I'm trying to enable Forms. Whenever I try, it downloads, but won't enable. All I see is te following notification:

1. Go to apps page
2. Try to install the Forms app by clicking "Download and install"

Hey @kevquirk,

can you have a look into your server log? Is there any information about this?

Greets,

Thanks for the quick reply. All I'm seeing in the logs is a 500 error:

2021-02-23 13:16:09 | Error | [IP REDACTED] | 500 | POST /index.php/settings/apps/enable HTTP/1.0 |   |   | 5.78 K | Apache SSL/TLS access

Ah - Sorry. I meant the Nextcloud-Server log. Can you tell us, what is in there? 🙈

[kevquirk]

Doh! Of course you did, sorry!

It spits a number of errors when I try. Here's the exported log - https://pastebin.com/3nttPi44

Hm, @kevquirk not sure, if you are aware, that your domain of the instance is in there. Shouldn't be too much of a problem, but some people like to not have it public everywhere. So probably you might want to remove that log-file again... ;)

However: @skjnldsv Probably we should get current stuff done and release v2.2.0 these days?! 😉

{"Exception":"Error","Message":"Undefined class constant 'INTEGER'", [...] "class":"OCA\Forms\Migration\Version010200Date20200323141300"

@kevquirk If you are motivated, you could change your update-channel to beta an try the forms v2.2.0-beta.1 (and reset update-channel afterwards). As far as i see by now and to the best of my knowledge, that should only produce a duplicated index on db, but nothing that should break your instance. However keep in mind it is a beta-version and please don't kill me if unexpected things happen. 🙈 But that should solve at least the error quoted above...

[kevquirk]

Let's do it! 🤠

I'll report back and let you know how it goes.

[kevquirk]

Whoop! You sir, are a genius. I now have forms working on my instance and nothing seems to be broken. Thanks for the help and the incredibly quick response!

I know, I just wanted to get it to you without having to sanitise it. I've deleted the pastebin now.
