@googlebot update label

@gmlewis is there an issue with the bot ? Do I need to do something manually?

[gmlewis]

@iam-veeramalla - no, you don't need to do anything.
I was just hoping to get its attention to add the "CLA: yes" label to the issue just to avoid any future confusion.

@googlebot already approved the PR, but it neglected to add the label. I'll give it a little more time... and see if it wakes up.

[gmlewis]

OK, @googlebot, I gave you your chance. I'll add the label myself.

[google-cla]

☹️ Sorry, but only Googlers may change the label cla: yes.

[gmlewis]

frowning_face Sorry, but only Googlers may change the label cla: yes.

Ah, right. I remember that block of code. 😂

Too bad we didn't allow Xooglers to change the label. Oh well.

looks like the bot is playing around :p with us @gmlewis
