Read DevOps Variable as bool in ARM paramters - azure-devops

Question

I am trying to read in a pipeline variable as a bool. I have the following parameters defined in json:
"parameters": {
"disableFunkyFunction": {
"value": "#{myVariables.disableFunkyFunction}#",
"type": "bool"
}...
}
In my Azure DevOps release pipeline, I have a pipeline variable called myVariables.disableFunkyFunction and the value for it is set to true. However, whenever I try and run the pipeline, it fails on the "Azure resource group deployment" step: Template parameter 'disableFunkyFunction' was provided an invalid value. Expected a value of type 'Boolean', but received a value of type 'String'. I have tried using a value of 1 instead, but to no avail.
The following works, but ideally I want to read the value from the DevOps pipeline variable, not hard code it in the parameters file:
"parameters": {
"disableFunkyFunction": {
"value": true,
"type": "bool"
}...
}
Any suggestions?

From the error message, it seems that the pipeline variable value hasn't been passed to ARM template file.
Since you have set the parameter value as #{myVariables.disableFunkyFunction}#, you can try to use the Replace Token task from Replace Tokens Extension.
Here are the steps:
Step1: Keep the parameter value as #{myVariables.disableFunkyFunction}#.
Step2: Use Replace token task to set the value.
Step3: Deploy the ARM template.
For example:
Note: You need to put the Replace token task before the ARM template deployment step.
