Hello @Marc64,
This example is based on the Hello world you mentioned on the original topic.
Based on the attached image, 1 and 2 also work well as expected without error. But 3 gave me an error.
These are copied syntax from the example I used. Keep in mind that 3rd one also gives me errors as well.
{{toBinary("SGVsbG8gV29ybGQ="; "base64")}}{{toString(toBinary("SGVsbG8gV29ybGQ="; "base64"))}}{{toBinary("""SGVsbG8gV29ybGQ="""; base64)}}
Cover your syntax with backtick ( ` ). It’s more readable.
I hope this helps you.
