2 months ago Hi @djbeaulne, the intermittent nature of your authentication is likely because RCMImageProducts can be search both authenticated and non-authenticated, whereas Radarsat2 always requires authentication. We invite you to use the eodms-cli which abstracts all this from the user. If you wish to integrate EODMS search into your workflow, then py-rapi-api is the way to go, but you will need to be sure to re-authenticate every 30 minutes to ensure your HTTP sessions is in good standing, since there the server will auto-log you out
Intermittent authentication error when querying through EODMSRAPI.
By intermittent, I mean that a few weeks ago, I was getting an authentication error. I set it aside, did other work, but didn't change anything with regards to my computer system, installations, or EODMS account. Yesterday my query worked, but today I am getting an authentication error again. Sometimes the authentication error is preceded by timeouts; in this instance, it is not.
Throughout this, I have always been able to log in to 'the actual website, https://www.eodms-sgdot.nrcan-rncan.gc.ca/index-en.html', using the same credentials I use through EODMSRAPI, which is provided in the error message.
Occurs for all collections; 'Radarsat2RawProducts', 'Radarsat2', 'Radarsat1', and 'RCMImageProducts' are the ones I'm most interested in.
A screenshot of error messages and my roi .geojson file are attached.
This might be a separate issue, and it's something that I can work around, but - if a query fails, and I try to re-submit the query, i.e. two sequential rapi.search() queries, with a failed first attempt, no error message is provided after the second attempt. I have to re-login using rapi=EODMSRAPI(user,pass) after a failed rapi.serach() attempt in order for the new search to be sent through. This is demonstrated in the third rapi.search() attempt in the screenshot.
