Invalid Response - 504

[Deleted user]

I am getting Invalid Response error (504).  The ETL updates almost 1100 cards and then gives this error.  Sometimes the error occurs very early.  Why is this happening?  Thank you.

What API route are you calling?

504 is a timeout, so likely whatever you're doing is taking too long/is trying to do too much work.

I have different endpoints.

/cards/{object_id}/labels?key={key}&token={token}

/cards/{object_id}/pluginData?key={key}&token={token}

/boards/{object_id}/cards?key={key}&token={token}

/boards/{object_id}/lists?key={key}&token={token}

/lists/{object_id}/cards?key={key}&token={token}

cards/{object_id}/"
"actions?filter=updateCard:idList&key={key}&token={token}

 I have about 2500 cards.  On the first run, I got an error after it went through 63 cards.  Second time, it stopped after 1059 cards.  This time, the code is still running without any issue. So, no clear pattern.  Is this an internet connection issue or something else?  Thank you.
