The Redis cache TTL (expiration date) has a wrong value.
Steps to reproduce:
In order to test the fix, flush cache and open a configurable product on the storefront. Then open a terminal (console) and follow the steps below:
- Run the command:
KEYS "*PRICE" (there should be only one key in the result, for example, zc:ti:e54_PRICE). Copy the key.
SMEMBERS followed by the key from the previous step (for example,
SMEMBERS zc:ti:e54_PRICE). Copy any key from the result (for example, e54_4E67B390D5C28FC7C3D9BB0D37AB3F7B5E576421).
KEYS "*<key>" with the key name from the previous step to get the full key name (for example,
KEYS "*e54_4E67B390D5C28FC7C3D9BB0D37AB3F7B5E576421"). There should be only one key in the result (for example, zc:k:e54_4E67B390D5C28FC7C3D9BB0D37AB3F7B5E576421). As you may notice, the full key name is simply the key name with prefix "zc:k:". Now copy the full key name.
HGETALL followed by the full key name from Step 4 to check the value. The value should contain serialized data of associated products of a related configurable product.
TTL followed by the full key name from Step 4 to check whether the key has an expiration. The result should be different from -1 and -2 and should be approximately 2592000 (30 days). Although the expiration set in the code is one year, the Redis library used in Adobe Commerce has a hard max expiration limit of 2592000s.
Expiration limit is 2592000s
Expiration limit is set to -1 or -2.
