Unable to add or update trigger action - [illegal_state_exception] or [parsing_exception]


after upgrading to Opensearch 2.0.0 we are no longer able to create trigger actions or update already existing actions. When pressing the CREATE/UPDATE button the result is the following error message:

[illegal_state_exception] Can’t get text on a START_OBJECT (when ‘Per alert’ is selected)


[parsing_exception] Failed to parse object: expecting token of type [START_OBJECT] but found [VALUE_STRING], with { line=1 & col=690 } (when ‘Per execution’ is selected).

It also doesn’t work in a completely new Opensearch 2.0.0 cluster. :frowning:

Any advice / solutions on this?

OK, the issue is already reported on GitHub:
