Here is the code.

var parameters = {
"entityRecordId" : "4232901b-2fc5-e711-a898-0022480173bb",
"entityLogicalName" : "opportunity"
};

var req = new XMLHttpRequest();
req.open("POST", "https://org.crm.dynamics.com/.../Microsoft.Dynamics.CRM.new_OpportunityUpdate", true);
req.setRequestHeader("OData-MaxVersion", "4.0");
req.setRequestHeader("OData-Version", "4.0");
req.setRequestHeader("Accept", "application/json");
req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
req.onreadystatechange = function () {
if (this.readyState === 4) {
req.onreadystatechange = null;
if (this.status === 204) {
} else {
var errorText = this.responseText;
}
}
};
req.send(JSON.stringify(parameters));

Hello,

It looks like you are using a custom defined Action.

Can you please post the definition of the Action?

Hi Nitin,

You can use below code,

function CallAction()

{

debugger;

var leadids = Xrm.Page.data.entity.getId();

leadids = leadids.replace(/[{}]/g, "");

var requestData ={

"Topic" : {"leadid" : leadids, "@data.type":"Microsoft.Dynamics.CRM.lead"}

};

var requestMethod = 'POST';

var actionnew = "leadid("+leadids+")/Microsoft.Dynamics.CRM.str_globalactionnew";

var req = new XMLHttpRequest();

req.open(requestMethod, Xrm.Page.context.getClientUrl() + '/api/data/v9.0/' + actionnew, true);

req.setRequestHeader("Accept", "application/json");

req.setRequestHeader("Content-Type", "application/json; charset=utf-8");

req.setRequestHeader("OData-MaxVersion", "4.0");

req.setRequestHeader("OData-Version", "4.0");

req.onreadystatechange = function () {

debugger;

if (this.readyState == 4) {

req.onreadystatechange = null;

if (this.status == 200) {

alert("Action called successfully");

} else {

var error = JSON.parse(this.response).error;

alert(error.message);

}

}

};

req.send(JSON.stringify(requestData));

}

If you find it helpful, Please Mark as Verified.

Best Regards,

Shahbaaz

Hi,

I have the same problem. Making changes to a custom action usually breaks it by causing two kinds of issues:

The action temporarily responds with 204 No Content instead of the JSON with output parameters. It is probably some caching issue since after waiting for a few hours it works properly. Quite embarrassing when the project deadline is getting closer.

Execution fails with the message above, so Request message has unresolved parameters

Based on the call stack (CrmODataRoutingConvention.SelectAction is the topmost method call) the system can't pick the action to execute. I get the same message if I just type any random action name.

I'm testing my actions using RESTED Firefox extension, so the problem is for sure not caused by improper JS or wrong action name. Today I made an action, tested, worked ok. Changed it to be a template, created another action based on it and made a minor change (the value of a param of a step) => Request message has unresolved parameters.

I've been facing the same error many times when I'm deploying custom actions to production environment. Works fine in dev env but fails in prod. Deleting and recreating the exact same action in production usually solves the problem.

I have to say that custom action could be a very powerful feature if it wasn't so buggy...

BR,
Laszlo

Yes, you can say that again.

We've encountered such problems sometimes.
