IsDirty: Exception when executed without parameters

[edgd1er]

the return of the command: /usr/sbin/omv-rpc -u admin config isDirty 2>&1| jq .should return true or false. With omv6 it was ok.

Hereunder is the return since I migrated to OMV7. I have the same error on two separate servers.

/usr/sbin/omv-rpc -u admin config isDirty 2>&1| jq .

params is validated even if is null or empty:

openmediavault/deb/openmediavault/usr/share/php/openmediavault/rpc/serviceabstract.inc

Line 172 in 0a326a2

final protected function validateMethodParams($params, $schema) {

rpc.config.isDisrty model includes information about params not being required:

openmediavault/deb/openmediavault/usr/share/openmediavault/datamodels/rpc.config.json

Lines 2 to 12 in 0a326a2

	"type": "rpc",
	"id": "rpc.config.isDirty",
	"params": {
	"type": "object",
	"properties": {
	"modules": {
	"type": "array",
	"items": {
	"type": "string"
	},
	"required": false

as mentionned in forum the workaround to use isDirty could be sudo omv-rpc -u admin config isDirty "{\"modules\":$(</var/lib/openmediavault/dirtymodules.json)}" or sudo omv-rpc -u admin config isDirty '{"modules":[]}'

Would it be possible to use isDirty without supplying $params as previously ?

With the PR #1757 the RPC can be called via omv-rpc -u admin config isDirty '{}'. That's all i can do.
