Exception when using World Map Slice

[maver1ck]

When choosing World Map Slice, I'm getting this exception.
Unfortunatelly exception isn't pass to UI, so query is running infinitely.

Which version is this? If that's not master possibly it has already been fixed there.

[maver1ck]

Official from pip (so I assume it's 0.10.0)

[xrmx]

@maver1ck could you please try to reproduce in master please? If that's a production instance don't upgrade there though :)

[maver1ck]

Yep.
Is there an instruction how to install master ?
pip install git+https://github.com/airbnb/caravel/ + js_build.sh ?
Something more ?

[xrmx]

https://github.com/airbnb/caravel/blob/master/docs/installation.rst#making-your-own-build

[maver1ck]

Got this.
OK. The bug was repaired.
I think that by this commit.
3c92ba9

[xrmx]

Cool, closing then.

[maver1ck]

Any ETA of next version of Caravel so ?

[xrmx]

@maver1ck no ETA afaik

[maver1ck]

OK.
I'm trying to use master but it is full of bugs.
Should I start reporting them ?

[xrmx]

@maver1ck if they are not already reported yes, also PR even more welcome :)

In the meantime they are merged this two should already fix a couple of annoyances: #1127 and #1130

[maver1ck]

@xrmx
I'd like to contribute but unfortunatelly I'm rather backend developer and I don't have experience with JS and react.
Do you have some easy backend tasks ?

[xrmx]

@maver1ck #1141 is probably easy to fix as some variable is used but not defined, maybe a typo?
