Hello,
Looks like there is error in Vault template,
In default template from git.zabbix.com, item "Get metrics" does have this URL:
{$VAULT.API.SCHEME}://\{$VAULT.HOST}:\{$VAULT.API.PORT}/v1/sys/metrics?format=prometheus
Due to that, item gets example value like this one:
# HELP vault_seal_decrypt_time vault_seal_decrypt_time
# TYPE vault_seal_decrypt_time summary
vault_seal_decrypt_time\{seal_wrapper_name="shamir",quantile="0.5"} NaN
vault_seal_decrypt_time\{seal_wrapper_name="shamir",quantile="0.9"} NaN
vault_seal_decrypt_time\{seal_wrapper_name="shamir",quantile="0.99"} NaN
vault_seal_decrypt_time_sum\{seal_wrapper_name="shamir"} 0.03411500155925751
vault_seal_decrypt_time_count\{seal_wrapper_name="shamir"} 1
# HELP vault_token_lookup vault_token_lookup
# TYPE vault_token_lookup summary
vault_token_lookup\{quantile="0.5"} 0.13425299525260925
vault_token_lookup\{quantile="0.9"} 0.15281400084495544
vault_token_lookup\{quantile="0.99"} 0.15281400084495544
vault_token_lookup_sum 1.9230029806494713
vault_token_lookup_count 15
So as we can see, it's prometheus output, not JSON,
If we would delete part "?format=prometheus" from URL, we would get JSON:
{"Timestamp":"2025-02-07 08:02:20 +0000 UTC","Gauges":[\{"Name":"vault.core.active","Value":1,"Labels":{"cluster":"vault-cluster-7a2b46b0"}},\{"Name":"vault.core.in_flight_requests","Value":0,"Labels":{"cluster":"vault-cluster-7a2b46b0"}},\{"Name":"vault.core.mount_table.num_entries","Value":1,"Labels":{"cluster":"vault-cluster-7a2b46b0","local":"false","type":"auth"}},\{"Name":"vault.core.mount_table.num_entries","Value":2,"Labels":{"cluster":"vault-cluster-7a2b46b0","local":"false","type":"logical"}},\{"Name":"vault.core.mount_table.num_entries","Value":1,"Labels":{"cluster":"vault-cluster-7a2b46b0","local":"true","type":"logical"}},\{"Name":"vault.core.mount_table.size","Value":250,"Labels":{"cluster":"vault-cluster-7a2b46b0","local":"false","type":"auth"}},\{"Name":"vault.core.mount_table.size","Value":449,"Labels":{"cluster":"vault-cluster-7a2b46b0","local":"false","type":"logical"}},\{"Name":"vault.core.mount_table.size","Value":301,"Labels":{"cluster":"vault-cluster-7a2b46b0","local":"true","type":"logical"}},\{"Name":"vault.core.performance_standby","Value":0,"Labels":{"cluster":"vault-cluster-7a2b46b0"}},\{"Name":"vault.core.replication.build_progress","Value":0,"Labels":{"cluster":"vault-cluster-7a2b46b0"}},\{"Name":"vault.core.replication.build_total","Value":0,"Labels":{"cluster":"vault-cluster-7a2b46b0"}},\{"Name":"vault.core.replication.dr.primary","Value":0,"Labels":{"cluster":"vault-cluster-7a2b46b0"}},\{"Name":"vault.core.replication.dr.secondary","Value":0,"Labels":{"cluster":"vault-cluster-7a2b46b0"}},

It's important due to dependent items,
This is then later used by dependent item "Clear metrics"
This item have this preprocessing set:
"Check for error in JSON" with parameter "$.errors", [https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/app/vault_http/template_app_vault_http.yaml?at=refs%2Fheads%2Frelease%2F7.2#160]
By default, Vault template gets prometheus value, in a result this dependent item will never work - it would start working if master item will get JSON, not prometheus,
