Hi,

On my HttpJob - Post I got an error message:

It is on the Post command and it never reaches the JobDone event.

Can someone help what is going wrong?

Thanks.

Best regards,
André

I assume you did not release the (previous) job (or at least your code did not reach Job.Release due to conditions)

 

[Erel]

Or maybe you released the job before it completed.

Hi KMatle and Erel,

It seems to do something with the TempFolder = of the HttpUtils2Service.

TempFolder = File.DirInternal

or

TempFolder = File.DirInternalCache

gives the error.

Changing it to

TempFolder = File.DirRootExternal

It works fine.

What could this be?
In the past it worked fine, but could it be lost somewhere on the newer releases of B4A which I overlooked?

Best regards,
André

It not related to B4A version.

Can you post the relevant code?

 

[sorex]

I think you removed the try/catch and try to process a failed download.

Are you sure the url used in the request returns valid data?

No. I use tons of Http-Calls. All good. Must be something with your code. Please post the relevant code using code tags...
