I´m working on the upgrade of the js code to the new V9 version of Dynamics 365 and I cannot use arrow functions when using Xrm.WebApi (also upgrading js to ts).

For example, this does not work:

Xrm.WebApi.retrieveMultipleRecords(

                'mks_entitlementline',

                `$select=mks_name, _mks_parententitlementid_value&$filter=_mks_parententitlementid_value eq '${eId}'`).then(

                    (results) => {

                        if (!this.commonUtils.isUndefinedOrNull(results) && results.entities.length > 0) {

                            this.usesELS();

                        } else {

                            this.notUsingELS();

                        }

                        // filter contact lookup                        

                        this.filterContactLookup("", eId);

                        this.refreshPriorities(eId);

                        if (this.commonUtils.isUndefinedOrNull(this.formContext.getAttribute<Xrm.Attributes.LookupAttribute>('primarycontactid').getValue())) {

                            this.formContext.getControl<Xrm.Controls.LookupControl>('primarycontactid').setDisabled(false);

                        }

                    }).catch(error => {

                        console.log("ERROR -> entitlementSlaManagementOnUpdate: ", error);

                        Xrm.Utility.alertDialog("E----", () => { });

                    });

but this does (uglier in my opinion):

Xrm.WebApi.retrieveRecord("role", searchedId, "$select=name")

                    .then(

                        function (role: { roleid: string, name: string }) {

                            outArr.push({ Id: role.roleid, Name: role.name, Type: "role" });



                            if (rolesAndTeams.length === outArr.length) {

                                if (!error) {

                                    _onOk(outArr);

                                }

                                _onErr(errorObject)

                            }

                        },

                        function (err) {

                            errorObject = err;

                            error = true;

                        })

The error I´m receiving is:

Xrm.WebApi.retrieveMultipleRecords(...).then(...).catch is not a function

Basically tells me that 'catch' is not valid but I don´t know why it isn´t since it is ok for the ts compiler... I also tried configuring tsconfig file to output on es5 and es2017 but it didn´t work either.

so... can arrow functions be used with Xrm.WebApi? if so... what I´m doing wrong/not doing?

Thanks in advance!

I don't think the problem is caused by arrow functions. I think catch is the problem. Compiler won't tell you anything, if return value is of type any. I don't know if that is the case, but if you look into CRM API, you will see following signature:

Xrm.WebApi.retrieveMultipleRecords(entityLogicalName, options, maxPageSize).then(successCallback, errorCallback);

There is no mention of catch, but instead you can pass errorCallback to then.

BTW this is the way, you pass errorHandler in the second example.

So try this:

Xrm.WebApi.retrieveMultipleRecords(

            'mks_entitlementline',

            `$select=mks_name, _mks_parententitlementid_value&$filter=_mks_parententitlementid_value eq '${eId}'`).then(

                (results) => {

                    if (!this.commonUtils.isUndefinedOrNull(results) && results.entities.length > 0) {

                        this.usesELS();

                    } else {

                        this.notUsingELS();

                    }

                    // filter contact lookup                        

                    this.filterContactLookup("", eId);

                    this.refreshPriorities(eId);

                    if (this.commonUtils.isUndefinedOrNull(this.formContext.getAttribute<Xrm.Attributes.LookupAttribute>('primarycontactid').getValue())) {

                        this.formContext.getControl<Xrm.Controls.LookupControl>('primarycontactid').setDisabled(false);

                    }

                },

                error => {

                    console.log("ERROR -> entitlementSlaManagementOnUpdate: ", error);

                    Xrm.Utility.alertDialog("E----", () => { });

                });
