1. Download Thread Dump Request fails with status code 406
   Downloading thread dump failed. Request failed with status code 406

2. Download Heap Dump opens a new tab with below url and then performs no other action
   http://<server_path>/instances/<instance_id>/actuator/heapdump

Which version of SBA and which Browser version are you using?

[DhavalShewale]

I have tried on both SBA 2.2.0 and 2.2.1
Heap dump works fine with SBA 2.1.6
My bad to not include these details in original bug report.

I have tried it on IE, Chrome and Frontmotion Firefox. Imho browser version should not be an issue as it works for a lower SBA version. Anyways, will share the details later if required.

I am using Chrome 79

I am facing the same issue (406). I'm using SBA 2.2.1 on Chrome Version 79.0.3945.88 (Official Build) (64-bit)

duplicate of #1338 which I've fixed some minutes ago.

When can we expect this to be released?

[joshiste]

@DhavalShewale I wanted to upgrade to Spring Boot 2.2.3 before, but having trouble due to a bug in spring 5.2.3

[DhavalShewale]

@joshiste Download of Thread Dump still does not work. I have upgraded to SBA 2.2.2.

@DhavalShewale
Is there any error in the network or console tab?

[DhavalShewale]

On clicking of download button it tries to hit http://<server>:<port>/<context-root>/actuator/threaddump which return 406. While for the UI display it hits http://<server>:<port>/<context-root>/instances/<instance-id>/actuator/threaddump every second.

Console Output

**ERROR**: GET http://<server>:<port>/<context-root>/actuator/threaddump 406

**WARNING**: Downloading thread dump failed. Error: Request failed with status code 406
