Issue #4: timestamp field

[idrissneumann]

At this stage, the fields have been removed from the configuration but we get a 500 error when saving the datasource:

We need to proxify the /describe endpoint from quickwit in the datasource backend.

At this stage, seems ok:

Will test if there's some regression on the search

Regressions tests ok:

I get a 500 if the index does not exist

I get a 500 if the index does not exist !

@fmassot It's fixed with 022d331db027d8ab5d31fe1275478a1f2b7528b5

[idrissneumann]

Can we add a few tests on the backend side? This will really help to sleep at night :)

It's done :)

Last status check, still working great:
