Error in getting all the snapshots under a repository

[yabhishek (abhishek Yadav)]

Hi,
I have registered a repository named repo123 to use one of my AWS buckets for storing snapshots. When I run

 GET _snapshot/repo123

it returns the output as expected, containing repo name -

{"repo123":{"type":"s3","settings":{"bucket":"<bucketName>","region":"us-east-1"}}}

But when I run

GET _snapshot/repo123/_all

I am getting following exception and don't know what the reason could be -

{"error":{"root_cause":[{"type":"remote_transport_exception","reason":"[qaes-upgradedadata2][10.109.13.112:9300][cluster:admin/snapshot/get]"}],"type":"illegal_state_exception","reason":"Can't get text on a FIELD_NAME at 1:360"},"status":500}

I wasn't getting this exception a while ago and this is not even allowing me to take a new snapshot. I am running Elasticsearch 6.6.2. Node mentioned in the exception [10.109.13.112:9300] is running and is healthy

[kompuser@qaes-upgradedadata2 ~]$ get _cat/health
1614734160 01:16:00 es-upgrade green 3 3 20 10 0 0 0 0 - 100.0%
[kompuser@qaes-upgradedadata2 ~]$ 

It is the master as well as data node -

[kompuser@qaes-upgradedadata2 ~]$ get _cat/nodes
10.109.13.74  24 94 0 0.00 0.03 0.24 md - qaes-upgradedadata3
10.109.13.112 25 96 0 0.00 0.02 0.20 md * qaes-upgradedadata2
10.109.12.214 20 93 3 0.00 0.04 0.36 md - qaes-upgradedadata1
[kompuser@qaes-upgradedadata2 ~]$

I'm also getting similar error message when trying to create a snapshot against elasticsearch 6.8.14

{ "error": { "root_cause": [ { "type": "illegal_state_exception", "reason": "Can't get text on a FIELD_NAME at 1:176" } ], "type": "illegal_state_exception", "reason": "Can't get text on a FIELD_NAME at 1:176" }

repository registration works fine though.
