machine_tags and/or userid is not working in search and walk

[michxi]

I added to some photos machine_tags. Now I want to see if there is one (or more) photos with this machine tag. Here the tag is an SHA256 of the photo.

ET.dump(self.flickr.photos.search(userid = 'me', machine_tags = 'hash:o="9f38318b6ad55089f68cc2efc16e945a1fea21ba548f7f672416b65c227e675c"'))

results:

<rsp stat="ok">
<photos page="1" pages="0" perpage="100" total="0" />
</rsp>

But if I run the search via https://www.flickr.com/services/api/explore/flickr.photos.search (with userid and machine_tags) I see the correct result (2 photos). By experimentation in explore, I see that the parameter "userid" and the double-quote in machine_tags are critical, but according to logging (as far as i see) both had been incorporated in the request

requests_oauthlib.oauth1_auth DEBUG: Updated body: 'machine_tags=hash%3Ao%3D%229f38318b6ad55089f68cc2efc16e945a1fea21ba548f7f672416b65c227e675c%22&nojsoncallback=1&format=rest&userid=me&page=1&per_page=50&method=flickr.photos.search'

So I'm not quite sure how to proceed.

Have you tried different signing methods in the API explorer?

[michxi]

This yield the correct result (* out by me). As I'm using `me´ as user_id, I cannot drop any auth in the possible calling variations in the API explorer:

https://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=**API_KEY***&user_id=me&machine_tags=hash%3Ao%3D%229f38318b6ad55089f68cc2efc16e945a1fea21ba548f7f672416b65c227e675c%22&extras=machine_tags%2C+url_o&per_page=500&format=json&nojsoncallback=1&auth_token=***TOKEN***&api_sig=***SIG***

This URL is also perfectly curlable with GET.

If I'm running my unittest again:

It results in total="0" instead of the correct reply of 2.

I'm also getting zero results in the API explorer (I've removed user_id="me" because I don't have a photo with that hash), so I can't reproduce this issue.

[michxi]

Use user_id="93816820@N00" and machine_tags='hash:o="75dbdbc9c5acf69de83ac8a2e539258da8d723deb9c7567d7d60bf7a8a36996e"' to reproduce. This look-up via flickr API explorer returns the correct result: https://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=f701693ed07b894a0e47c5470ded6497&user_id=93816820%40N00&machine_tags=hash%3Ao%3D%2275dbdbc9c5acf69de83ac8a2e539258da8d723deb9c7567d7d60bf7a8a36996e%22&format=rest

If I pass my user_id instead of "me" in the python API, still empty result.

[sybrenstuvel]

The URL gives me:

<rsp stat="fail">
<err code="100" msg="Invalid API Key (Key not found)"/>
</rsp>

Please give me a way to reliably reproduce your issue, or I cannot fix it.
