We have some modifications on the USPS.php file so the line 555 is different than the stock file. Maybe this issue only exists on my site then.

Thanks for your help again.
i would suggest that rather than modifying said file, i would use the observer-notifier system inherent in this shipping module. if you do not know to use/set that up, i would suggest a review here:

https://docs.zen-cart.com/dev/code/notifiers/

furthermore, if there is not a notifier than accomplishes what you want, than i would suggest raising an issue about that so that we may add a notifier where you might need it.

i bring this up as i have a vague recollection of this problem and that a solution was already implemented. which your new code may obliterate.
