( https://gerrit.osmocom.org/c/pysim/+/34155 ) Change subject: sim-reset-server: fix error printing sw_match_error ...................................................................... Patch Set 2: Code-Review-2 (1 comment) File contrib/sim-rest-server.py: https://gerrit.osmocom.org/c/pysim/+/34155/comment/bcf52a25_e516301b PS2, Line 104: ), sw) We actually have a syntax issue here: ``` return str(ApiError("Card Communication Error %s" % failure.value), sw) ``` note that `sw` is actually passed as an argument to `str()`, while it should be passed to the constructor of the `ApiError`! The `str()` function does not concatenate its arguments unlike `print()`, the second argument is actually the `encoding`. With this additional argument `str()` tries to *decode* its first argument instead if calling the `__str__`. @dexter: can you try applying this patch? I believe it should fix the problem: ``` return str(ApiError("Card Communication Error %s" % failure.value), sw) return str(ApiError("Card Communication Error %s" % failure.value, sw)) ``` You're actually fixing this in the patch, but I suggest to keep the `failure.value`. I can even reproduce the error mentioned above (similar to yours): ``` 'Card Communication Error SW match failed! Expected 9000 and got feed.' 'SW match failed! Expected 9000 and got feed.' Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: decoding to str: need a bytes-like object, SwMatchError found ``` -- To view, visit https://gerrit.osmocom.org/c/pysim/+/34155 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: pysim Gerrit-Branch: master Gerrit-Change-Id: I5a1d19abeb00c2c9dc26517abc44a5c916f2d658 Gerrit-Change-Number: 34155 Gerrit-PatchSet: 2 Gerrit-Owner: dexter &lt;pmaier(a)sysmocom.de&gt; Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: fixeria &lt;vyanitskiy(a)sysmocom.de&gt; Gerrit-CC: laforge &lt;laforge(a)osmocom.org&gt; Gerrit-CC: osmith &lt;osmith(a)sysmocom.de&gt; Gerrit-Attention: osmith &lt;osmith(a)sysmocom.de&gt; Gerrit-Attention: laforge &lt;laforge(a)osmocom.org&gt; Gerrit-Attention: dexter &lt;pmaier(a)sysmocom.de&gt; Gerrit-Comment-Date: Wed, 30 Aug 2023 23:39:41 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: Yes Gerrit-MessageType: comment
