Error in Parsing Block

[melon]

I'm getting this error in the Parsing block:

ERROR: String cannot be of zero length.
Parameter name: oldValue

I have never encountered this error before, tried searching it in this forum to no avail. I've made sure that the LEFT and RIGHT STRING is a valid string that exists in the response source.

Well, then your source is of zero value

[melon]

What do you mean by zero value?

[Ruri]

I mean empty

@Ruri

Is that the one you're talking about? I don't see an empty source.

[Ruri]

Can you please show me your parse block?

This looks like an PARSE issue so u can use automated box like sentry.

I have no idea why it bugs out like that, is the thing you want to capture on 2 different lines maybe?

[melon]

@Ruri Nope it isn't. It's on the same line. I duplicated the config, 1 works fine and 1 bugs like that.

Maybe there are some non-printable characters you pasted in the left/right textboxes. Please delete the block, make a new one and type the values in manually and let me know if it's better.
