Firebug error : dojo.io.script error

[YvanBérard]

Hello guys,

first, thanks for helping.

Here is my problem. In firebug, with the JS API 3.8 I've started receiving some weird error...but my script is still working.

How can I make these errors disappear

Here are the errors from Firebug:

without seeing code its going to be nearly impossible to help, but it looks like maybe you have a callback that has incorrect parameters

[YvanBérard]

with some debugging, I've managed to find where the error occur

layer = new esri.layers.ArcGISDynamicMapServiceLayer(url+"/MapServer", {id:oParamUser.config.layer, imageParameters: imgParams});

This line seems fine....I don't know what's wrong...

[JeffPace]

make sure your requires are correct, and make sure {id:oParamUser.config.layer, imageParameters: imgParams}

oParamUser.config.layer and imgParams are not null

and that imgParams is a valid esri/layers/ImageParameters object

[YvanBérard]

oParamUser.config.layer and imgParams are not null

and i'm using the Legacy Module Require and it doesn't seem to need a specific "require" except the dojo.require("esri.map");

[YvanBérard]

imgParams is declared and modified this way:
var imgParams = new esri.layers.ImageParameters();
imgParams.format = "png32";

oParamUser.config.layer contain an id like "this_is_my_layer"

[JeffPace]

it might be my lack of sleep, but you still need

dojo.require("esri.layers.ArcGISDynamicMapServiceLayer")
dojo.require("esri.layers.ImageParameters");

etc..

[YvanBérard]

These are all the require declaration I use:

Note taht the esri.layers.agsdynamic and agstiled are the new "way" to call them in 3.8 with the Legacy Module

dojo.require("esri.map");
 dojo.require("esri.layers.agsdynamic");
 dojo.require("esri.layers.agstiled");
 dojo.require("esri.layers.ImageParameters");
 dojo.require("esri.dijit.Scalebar");
 dojo.require("esri.dijit.Print");
 dojo.require("esri.dijit.Measurement");
 dojo.require("esri.dijit.Legend");
 dojo.require("esri.dijit.OverviewMap");
 dojo.require("esri.toolbars.navigation");
 dojo.require("esri.toolbars.draw");
 dojo.require("esri.tasks.query");
 dojo.require("esri.tasks.find");
 dojo.require("esri.layers.osm");
