Escaping $ in JSON

I want to end up with a JSON object that looks like this:

{"$content-type": "inputparameter1","$content": "inputparameter2"}

where the "inputparameter" strings are supplied via a PowerApps trigger (text and text_1). the JSON object is a parameter in a subsequent action.

I'm using a Compose action with this function:

json(concat('{','"$content-type":"',triggerBody()?['text'],'","$content":"',triggerBody()?['text_1'],'"}'))

but it fails. If I take the $ characters out, it succeeds.

I've tried '"\$content-type and '"%"$"%content-type but can't get it to work.

How can I escape a $ character when constructing a JSON object?

Hi , @JonathanGibbs
I test it in my side , it also give the internal error .
For your need ,you can try to use the Select action to realize it .
Then we can get the result as follows:

I would use a variable of type Object instead of Compose which should work.

json(concat('{', '"$content-type":"', triggerBody()['text'], '","$content":"', triggerBody()['text_1'], '"}'))

Re: Escaping $ in JSON

@grantjenkins Thanks. Learned something new there about Compose vs Variable
@v-yueyun-msft That's a neat solution YueYen - cleaner than the clunky text manipulation, perhaps. Need to isolate item [0] from the array of course
