plotly_IMAGE stopped working

Hello,
I am not sure if the server is undergoing maintenance. Function plotly_IMAGE suddenly stopped working yesterday. It worked for like 6 or 7 graphs and now returns error [502].

BTW, as a side note, I really would like to have easier options to saving static plotly graphs as PNG. I spent so many hours with this, I tried Orca, Kaleido (which requires installing reticulate, miniconda etc), never made these work because of multiple installing problems, like my user has a space character and miniconda won't install. Anyways, multiple bugs in the process, to finally find the plotly_IMAGE function that somehow worked. I really feel like getting static images is an important feature for R, where many users are forced to used latex to report our works later. Let me know if I can help with this in any way.

The error is:

plotly_IMAGE(global_return_graph, format = 'png', out_file = file.path(savep$
# > Request failed [502]. Retrying in 1.6 seconds...
# > Request failed [502]. Retrying in 1.7 seconds...
# > Request failed [502]. Retrying in 3.9 seconds...
# > Request failed [502]. Retrying in 2.8 seconds...

The same code was working before and just stopped.

まず、報告された plotly_IMAGE 呼び出しを format='png' と表示されている out_file 引数で再現し、502 が引き続き発生するか確認します。次に、plotly_IMAGE のエントリポイントとリクエストパスを調査します。完了条件は、失敗を特定して修正するか、外部画像サービスが利用できないことを文書化し、静的 PNG エクスポートのリグレッションチェックを追加することです。
