Http request error "reason: Parse Error: Invalid header value char"

Hi all,

I try to create a post http request in a flow with a logic card but it doesn’t work. Every time I got the message “, reason: Parse Error: Invalid header value char” .

Does anyone have any ideas?


Try with the headers empty.

I did but with the same result and error, additionaly I tried “Content-Type: application/json”.
When I use use a rest client like YARC I got an answer “ok<D_C_5_1>1</D_C_5_1>”"

Can you make a screenshot of the response headers in the YARC client? It’s difficult to say where exactly the error is coming from.

Also, it looks like your custom “content-type” header isn’t actually set in YARC (if it were, I would have expected it to show up in the table where it now says “There are no headers to display”).

here with the header ( I think I don’t need it)

I hope it will help.


All looks okay to be honest, no idea what’s causing your problem :frowning:
