TYPO3 DCE use curly bracket inside fluid template file

Question

I have a DCE content element and now I need to add a json object inside this template with the text from the variables.

I tried many ways like

<f:format.raw>{</f:format.raw>

or

<f:format.alias map="{l: '{}', r: '}'}"> { json } </f:format.alias>

but nothing works.

<dce:format.WrapWithCurlyBraces>json</dce:format.WrapWithCurlyBraces>

was my last test but this generates an empty output. Is there any way to output some json with the variables from the dce inside?

<f:format.json>{"context": "https://schema.org/"}</f:format.json>

also tested, generates also an empty output.

DCE Version: 2.6.0
TYPO3: 9.5

Answer 1

<f:format.raw>{</f:format.raw> should work. If not, you can also try <f:format.raw value="{" />. For example:

<f:format.raw value="{" />json<f:format.raw value="}" />
