Read Range: Expression Activity type 'VisualBasicValue`1' requires compilation in order to run. Please ensure that the workflow has been compiled

Hi,

It seems your expression contains non-0x22 double quote as the following image.

Can you try to replace these double quotes with " (0x22)?

Please also see the following post.

Visual basic workflow compilation error

Hi, In windows legacy, it seems double quote is normalized and any double quote characer is accepted. However, at this time, in windows (.net6) ,in fact, only " (0x22) is accepted to express string literal. To make matter worse, it seems to occur only compiling. (Expression validator don’t raise an alert.) FYI, the following is sample for reproducing. The first Assign uses " 0x22 and second Assign uses “ and it fails in compiling.
