Hi Alexander,

Can you please share the error stack trace? You should be able to find it in service center error logs.

Best,

Bruno

Here it is

Hi Alexander,

This seems to be the stack trace of the error on the OutSystems implementation side. I would expect you to have another log entry (next to this one) with the error stack trace that is internal to the extension.

Is it this one?

Yes. This is it.

Are you using any placeholders on your template that have new lines in between? For example:

"#Place\nholder1#"

Not in the placeholder, but there is some \r and \n  in the replacement data.
I've attached the placeholder and replacement json

Hi Alexander,

I might have found the issue. I will be reaching out to you in a private chat to share a new OfficeUtils built for you to test. I can't share it here since the file is too large.

Hi Alexander,

I was able to reproduce the issue using the template you have provided. It occurs when replacing placeholders with multi-line text, but in very specific circumstances.

I have published a new release of OfficeUtils (5.6.0) that solves the issue.

Best,

Bruno

Thanks Bruno
