You have to escape the forward-slash since it has special meaning in JSON

In JSON forward slashes can be escaped, but they don't need to be escaped - they have no special meaning:

Quote from: RFC 7159 - The JavaScript Object Notation (JSON) Data Interchange Format
All Unicode characters may be placed within the quotation marks, except for the characters that must be escaped: quotation mark, reverse solidus, and the control characters (U+0000 through U+001F).


I can't reproduce this error... how exactly do you load the string into  EPGJSONstr? Did you check whether  EPGJSONstr  does in fact contain the JSON you posted before calling  GetJSON?

OK, accepted. Probably found a "wrong" website.

but i see something else, which is different between his 2 JSON's:

That's Unicode, right?
Is his Problem maybe an encoding-issue?

I get it like this : EPGJSONstr := FunctionEPG(ChannelsJSONstr,EPGJSONstr, Now());

This doesn't help.. how are we supposed to know what  FunctionEPG does?

Here's another suggestion: insert the following line...

Code: Pascal  [Select][+][-]
  1. with TStringList.Create() do begin Text := EPGJSONstr; SaveToFile('example.json'); Free(); end;

...right before this line...

Code: Pascal  [Select][+][-]
  1. SupplierJSON := GetJSON(EPGJSONstr,True);

...and then look at  example.json  after recompiling & running the program.
This is what the JSON parser actually gets to see, and I'm willing to bet that it doesn't contain valid JSON.

FunctionEPG uses IdHTTP to grab basicdata which are in JSON format and converts these data to a unified data rule in JSON format at the receiving unit

and is called

EPGJSONstr := FunctionEPG('Channel Name','Channel ID', Now());

Then I have tried to take copied text in Sl.Text and convert this to JSON still same error, however the other sample works as expected

I have a function which creates this JSON string:
[...]
and when I run this piece of code
[...]
there is NO error
If you'd have posted a complete, compilable project (*) I could just have checked your issue immediately. With the snippets provided I had to create a project of my own - too many things that I could do differently from what you were doing. In the attachment there is the project that I created, the ButtonClick handler executes your code - no issues at all (Laz/main + fpc3.2.2, or Laz 2.0.12 + fpc 3.2.0, on Windows 11)...

(*) NB: But this does not mean that you should post you current project - it's a lot of work to debug the projects of others and make the bug appear. Just reduce everything so that only the bug is left and post this reduced project.

I have a function which creates this JSON string:
[...]
and when I run this piece of code
[...]
there is NO error
If you'd have posted a complete, compilable project (*) I could just have checked your issue immediately.

I have zipped the files in use for creating the JSON data etc.... and attached them here  .. It is NOT the complete project
