OMV7: rpc-admin -u admin config isDirty => The value \"null\" is not an object.

edgd · 19. April 2024

hello,

I based a script on the return of the command: /usr/sbin/omv-rpc -u admin config isDirty 2>&1| jq .

which 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.

Code

/usr/sbin/omv-rpc -u admin config isDirty 2>&1| jq .
{
"response": null,
"error": {
"code": 0,
"message": ": The value \"null\" is not an object.",
"trace": "OMV\\Json\\SchemaValidationException: : The value \"null\" is not an object. in /usr/share/php/openmediavault/json/schema.inc:395\nStack trace:\n#0 /usr/share/php/openmediavault/json/schema.inc(289): OMV\\Json\\Schema->validateObject()\n#1 /usr/share/php/openmediavault/json/schema.inc(261): OMV\\Json\\Schema->validateType()\n#2 /usr/share/php/openmediavault/rpc/paramsvalidator.inc(59): OMV\\Json\\Schema->validate()\n#3 /usr/share/php/openmediavault/rpc/serviceabstract.inc(179): OMV\\Rpc\\ParamsValidator->validate()\n#4 /usr/share/openmediavault/engined/rpc/config.inc(59): OMV\\Rpc\\ServiceAbstract->validateMethodParams()\n#5 [internal function]: Engined\\Rpc\\Config->isDirty()\n#6 /usr/share/php/openmediavault/rpc/serviceabstract.inc(122): call_user_func_array()\n#7 /usr/share/php/openmediavault/rpc/rpc.inc(86): OMV\\Rpc\\ServiceAbstract->callMethod()\n#8 /usr/sbin/omv-engined(535): OMV\\Rpc\\Rpc::call()\n#9 {main}"
}
}

getInformation gives also the status: /usr/sbin/omv-rpc -u admin system getInformation | jq .configDirty

the return is: false

the content of /var/lib/openmediavault/dirtymodules.json is []. The file was modified last April, 10th.

is config isDirty deprecated ?

I tried with parameters empty json with no better luck:

/usr/sbin/omv-rpc -u admin config isDirty "{}"

{"response":null,"error":{"code":0,"message":": The value [] is not an object." .....

it looks like isDirty cannot accept an empty parameter .

It still exists - https://github.com/openmediava…ngined/rpc/config.inc#L54

The validation config is looking for an array but it isn't required.

openmediavault is the next generation network attached storage (NAS) solution based on Debian Linux. Thanks to the modular design of the framework it can be…

On OMV 6.x, there was no validation. So, you just need to pass an empty modules array:

sudo omv-rpc -u admin config isDirty '{"modules":[]}'

thanks for the answer.

According to the comments "If empty, * all modules will be checked.",.

Even if parameters var is empty, validation is perfomed on null object:

$this->validateMethodParams($params, "rpc.config.isDirty");

so the code hereunder is the workaround to use isDirty, much less easier than previously.

Code

sudo omv-rpc -u admin config isDirty "{\"modules\":$(</var/lib/openmediavault/dirtymodules.json)}"

OMV7: rpc-admin -u admin config isDirty => The value \"null\" is not an object.
