Hello Guys

restheart:7.3.2 / 7.3.3
mongo:6.0

Sorry guys to bother you.. i have POST to create documents random error.
I am wondering if this is not due to the fact that i use mongo6, and you maybe fully support mongo5 at this time.
Do you advise me to use mongo5 rather than 6? Thanks

Here is the exception:

We support MongoDB 6

I cannot reproduce.

Nevertheless I refactored the code to avoid the NullPointerException in that line, even if it is weird that you get a document inserted but no data from the MongoDB java driver (thus thew NPE)

Can you try with the following snapshot image

$ docker pull softinstigate/restheart-snapshot:45955fb
WT2 commented

Hi @ujibang
YES! thanks it corrects. I set this snapshot only on one of my two nodes. i still reproduce on the node with 7.3.3 and no longer on the snapshot 45955fb! so your refactor worked! i no longer have that error.

Actually i just realized that i was getting this with RESTHEART default readPreference set to secondaryPreffered.
When i put it back to primaryPreferred, i do not reproduce.

So if you want to reproduce, you set in your restheart settings MONGO_URI secondaryPreffered.

You confirm?

I just discovered some other bugs with secondaryPreffered as default, i can share them with you if you like.

yes please share all the bugs you find.

ok i will in a separate issues.
for #452 and #454 is it OK for you to merge it in the next minor version ?

WT2 commented

hello,
do you confirm this has been taken into account in 7.3.4?
thanks

yes, this fix is in 7.3.4
