LoadRunner Truclient Ajax failed – an argument is invalid: ‘Code’: JavaScript exception ‘ReferenceError: LR is not defined’ during evaluation
| ♥ 0 |
Using the new TruClient Protocol, the Development Environment Stopped idenifing LR.getParam and other Javascript commands. It seems to have completely lost the libraries for these commands. The error in the replay log says: Evaluate JS Username=LR.getParam("ParameterName1") ** failed – an argument is invalid: ‘Code’: JavaScript exception ‘ReferenceError : LR is not defined’ during evaluation

LR 11.0 only supports the version of FireFox that is distributed with LR, FireFox 3.6.3. If the installation has been updated LR won't work properly with it. Marked as spam

The Firefox upgrade is one cause for this error. There is another I will describe here that I've encountered. LR. is only defined in two places that I have found, Evalute Javascript blocks and when entering data via 'Type' style entry in the Arguments Value box. If you want to use LR. inside the 'Object' section of a step, then you have to be clever about it. 1. First add a Evaluate JavaScript step to your script. Make sure it comes after the navigate step. In this step have something like: Marked as spam

I did, that was just a typo in the question asked here. The solution ended up being to not upgrade the firefox 3.6.3 that is installed with LR. I had made it my default browser and subsequently let it update. This made LR stop working in interactive mode.

Evaluate JS Username=LR.getParam(''ParameterName1'') ** failed - an argument is invalid: 'Code': JavaScript exception 'ReferenceError : LR is not defined' during evaluation It seems that you are trying to replay a single step with parameter. It doesn't work in this way. Parameters will work only if you will replay entire script. Marked as spam

Don't run the step as single step... you must use ''Run from this step'', or run whole script. Marked as spam
