Testing returns an Array Failure

(0) ShareShare
ReportReport
Posted on by Community Power Pla... Microsoft Employee

Initialized 2 array variables in a Power Automate:

GregMc_0-1687966289407.png

When I run the workflow I receive the following results:

GregMc_1-1687966383818.png

That actual error being thrown is:

GregMc_2-1687966418751.png

Why does the first array fail and how to correct?

 

In the future I will be replacing the text entries with the actual contents from a string being brought in from a SharePoint Column.

 

Thanks for the help!

    UPDATE: It appears the '\' character in the PIN is causing the problem. If I replace the '\' with '\\' then my array is accepted but the string now has a double '\':

    How do I prevent this as I simply desire to have a single slash as part of the PIN value?

    Hi @Anonymous ,

     

    '\\' means '\' , it's a kind of JSON escaping .When you invoke this value, it will display as '\' normally.

    JSON escaping is a method of converting special characters into a readable form so that computers can parse and process them correctly. In JSON, if the string contains special characters, such as quotes, backslashes, and line breaks, it needs to be escaped.

     

    Special characters are handled by prefixing them with a '\', such as escaping double quotes (") to (\"), backslashes (\) to (\\), newline characters (\n) to (\\n), and so on.

     

    Best Regards,
