Http request : is there hidden HEADERS parameters?

Hi all,
i try to read a product with a PIM API Get products (akeneo).
I got good response from appsmith and postman but not from N8N.
It always give an error response :

ERROR: UNKNOWN ERROR - check the detailed error for more information
"application/json,text/*;q=0.99" in "Accept" header is not valid. Only "application/json" is allowed.

This seem to be autogenerated.
I only have Authorization header.
I already see this in your execution_entity Table in data field.

I try to write an accept : application/json header, but it does not work.

Thanks for help.

Find it !

you can surcharge the Accept value if you write it in MINUS…

accept and not Accept
