Error message

e.message

What it means

The JSON.SET promise rejected: the server refused the command outright. Common messages: 'Existing key has wrong Redis type'/WRONGTYPE when the key holds a non-document type, 'unknown command JSON.SET' when the module is not loaded, document-depth/size limit errors from RedisJSON, or an ioredis connection failure such as 'Connection is closed'.

Solutions

Run TYPE on the key; if it is not a ReJSON type, delete or rename the stale key before saving
Confirm the module is loaded with MODULE LIST (otherwise JSON.SET is an unknown command)
If the message is connection-level, reconnect and retry the save

Defensive patterns

Strategy: try-catch

Validate before calling

const type = await client.call('TYPE', key);
if (type !== 'ReJSON-JSON' && type !== 'ReJSON-RL') {
  return this.$message.error(`Key type is ${type}, not a RedisJSON document`);
}

Try / catch

client.call('JSON.SET', key, '$', content).catch((e) => {
  if (/wrong Redis type|WRONGTYPE/i.test(e.message)) {
    this.$message.error('Key was overwritten by a non-JSON type; delete or rename it first');
  } else if (/unknown command/i.test(e.message)) {
    this.$message.error('RedisJSON module is not loaded');
  } else {
    this.$message.error(e.message);
  }
});

Prevention

Check TYPE before JSON.SET on any key you did not create in this session
Verify with MODULE LIST that RedisJSON is loaded when connecting to a new server
Keep edited content in the dialog on failure so nothing is lost after a reconnect-and-retry

When it happens

Trigger: Saving a ReJSON tab after the key was overwritten with SET to a plain string; embedding RedisJSON with a nesting depth beyond the module limit; issuing the save right as the connection drops; server without the RedisJSON module.

Common situations: Mixed-type recycling of key names between apps; switching a connection to a replica or a different server that lacks the module; editing very large nested documents.
