:address/erc20 returns 500

I am getting 500 pretty regularly (not always) when trying to get token balances for some addresses.
I am passing list of tokens(38 of them) as part of request url (token_addresses=0xdAC17F958D2ee523a2206206994597C13D831ec7&token_addresses=0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48&token_addresses=…)

Status code and message of the response:
statusCode: 500,
statusMessage: ‘Internal Server Error’,

On which chain are you testing?
and can you check error logs on your server for any error messages?

we are investigating some issues on our side

ive experienced this also. in get erc20 transfers by wallet api. in one specific address. i dont want to write it here, its not mine address. will it help you or not entirely? its eth main net

[C0006] Request failed, Internal Server Error(500): Unknown error (no error info returned from API)

it happens only for a specific address every time?
