GitHub user Bauaser-kun edited a comment on the discussion: Something went 
wrong during the adapter installation

Sorry for the late reply.
All icons are showing properly both in adapter creation and pipelines views.
 I've checked logs. The extension-all-jvm log ends on february 29th 
approximetely the time I first time tried to create adapter, the last log is: 

`Error grabbing logs: invalid character '\x00' looking for beginning of value`

The backend log for today's streampipe startup is working but it indeed shows 
some errors from the very beggining - even though all containers seem to be up 
properly while they are initialized i find the following error :

```backend_1             | 2024-03-04T07:50:13.275Z  INFO 1 --- 
[pool-1-thread-1] o.a.s.c.m.management.WorkerRestClient    : Trying to start 
adapter on endpoint http://172.31.0.7:8090/api/v1/worker/stream/invoke 
backend_1             | 2024-03-04T07:50:13.789Z ERROR 1 --- [pool-1-thread-1] 
o.a.s.c.m.management.WorkerRestClient    : Adapter was not started successfully
backend_1             |

to 172.31.0.7:8090 [/172.31.0.7] failed: Connection refused```

I assume that this is the OOTB adapter as it was definitely not created by me 
neither anyone else at my company.
But after that the same error occours for every single adapter we have already 
created in our pipelines. Then after around 15 seconds seconds the adapters are 
starting again, this time succesfully.

And then when I try to create new adapter I got this

```backend_1             | 2024-03-04T08:25:17.925Z  INFO 1 ---
