Error message: Cannot lookup a property on a NULL value

Hello everyone,

I'm having this weird issue where I use a JSON generator to create a payload for the following HTTP client snap, but apparently all the values resulting are NULL, which is weird because the output of the JSON looks fine.

This is what I use in the JSON generator:

And the output looks just fine:

However, in the following HTTP client snap, the output preview gives an error because apparently the value is null.

Can someone help me find out what I did wrong?

Thanks in advance!

Hi @jfpelletier ,

I don't know if this applies to the issue that you are having where there's no valid key name to the form where you are setting the name value

Why you didn't use the Mapper snap for building the JSON? 

Hello @SpiroTaleski,

Thanks for your comment. Actually, I already tried using a mapper right after the JSON generator, and the mapper has no issue seeing the values and doing the mapping:

Still, the following HTTP Client snap says that the values are null...

Could this be related to what @alchemiz reported last Saturday?

Thanks!

Are you trying to send above fields in the body of the API request? 

Can you please share the HTTP Client Snap configuration?
